(Monsters Unleashed#3/3 - BTS) - In 1935 near Schwartzhof, Austria, the Witch of the Hills cast spells she had learned from the "forbidden tome of Alhazred" (presumably the Necronomicon) at the behest of the Romani Lucio Nuti, invoking the demons Yngvi (see comments) and Dyktawo in order to summon Satan.

(Marvel Comics Presents I#62 (fb) - BTS) - At some point the spirit of Alhazred was freed from the crystal and either gained a new host body or recreated its original one. He garnered such a fearsome reputation that even the tattoo he marked his servants with could strike terror into those who saw it.

(Marvel Comics Presents I#154 (fb)) - When some dock workers in an unspecified city (likely in Canada) cut Alhazred out of his share of revenue from items being smuggled through the dock, Alhazred teleported there to personally eliminate them as an example to others. After he summoned demons to slaughter the men, Alhazred was attacked by Wolverine, who was on special assignment investigating corruption on the docks and thus witnessed Alhazred's actions. However Alhazred telekinetically prevented him from making contact, then held him aloft, helpless to attack or escape. Alhazred warned Wolverine that he would kill him if Wolverine ever tried to find him or told others what he had seen, then vanished in a puff of smoke, leaving Wolverine deeply shaken.

(Marvel Comics Presents I#152 (fb) - BTS) - Wolverine considered Alhazred one of the most bloodthirsty murderers he had ever met, having witnessed him casually tearing men apart limb by limb without breaking sweat. Alhazred found the encounter memorable, despite its brevity, and looked forward to reliving it.

(Marvel Comics Presents I#62 - BTS) - Alhazred sought to takeover the Madripoor crime empire of Tyger Tiger, to enable him to depose prince Baran, and establish Madripoor as his power base. He planned to barter with other countries for the extradition of criminals who had fled there. To this end, he had his ally, the Sheik organize a band of unrelated mercenaries and kidnap Tyger Tiger and Archie Corrigan, but internal conflicts caused them to crash their plane in the jungles of Madripoor. As they stumbled from the wreckage the argument continued, with the survivors unaware that they were being observed by Wolverine, who had temporarily lost control to his bestial side. To settle the dispute, the Sheik opened his shirt, revealing Alhazred's tattoo on his chest.

(Marvel Comics Presents I#63 (fb) - BTS) - Recalling Alhazred and scared to mess with his affairs, Wolverine's bestial side retreated, allowing his humanity to regain control.

(Marvel Comics Presents I#62 - BTS) - Continuing to act like a wild animal in order to scare the criminals, Wolverine raced into the group, snatched up Archie, and carried him into the jungle to safety. Needing Corrigan for Alhazred, the Sheik's party pursued, but were convinced by a (fake) scream and some (planted) scraps of Corrigan's bloody clothing that Wolverine had slain the man.

(Marvel Comics Presents I#63 - BTS) - Wolverine commenced to pick off the criminals one by one, having Archie guard the prisoners he took until finally the last villain, the Sheik, was captured and Tyger Tiger freed. They sent their captives to Madripoor's jails, which despite being infamously dangerous Wolverine felt would be safer than sending them back to face Alhazred's wrath for failing him.

(Marvel Comics Presents I#153 (fb) - BTS) - Alhazred was intrigued to hear about Wolverine's intervention, so...

(Marvel Comics Presents I#152 (fb) - BTS) - when the Sheik and his men were freed from custody and returned to Alhazred's service...

(Marvel Comics Presents I#153 (fb) - BTS) - he allowed them a chance to make amends for their failure by trying to capture Tyger and Corrigan again, making it clear that a second failure would result in death, while secretly hoping for a chance to face Wolverine again and kill him.

(Marvel Comics Presents I#152) - Sometime later Alhazred tried again to capture Corrigan and Tyger, this time personally accompanying the Sheik and his men. The villain waited until Wolverine had defeated them before revealing his own presence, easily overpowering his old foe, who at this juncture was weaker than their last encounter as he no longer had Adamantium strengthening his skeleton. After throwing Wolverine off a balcony Alhazred hypnotized Tyger into submission with a single glance, ordered his men to handle transporting her, and teleported away.

(Marvel Comics Presents I#153) - Alhazred teleported to a remote airfield outside of Lowtown and slaughtered a group of air pirates therein.

(Marvel Comics Presents I#154) - The Sheik delivered his captive to the airfield, where Alhazred boasted to them that he would slay them as his first step in taking over Madripoor, starting with Tyger's criminal empire. Summoning his demons, Alhazred taunted Tyger, telling her to beg for her life, just before Wolverine burst in. Seeing his old foe, Alhazred shouted a welcome, informing the intruder that he had arrived in time to die with his friends.

(Marvel Comics Presents I#155) - Alhazred sent his demons after Wolverine, confident that they would send him into his berserker fury, which he could then control. However, when Logan resisted and maintained mental control of himself, the psychic backlash caused Alhazred to be banished to the extra-dimensional realm of his demons.

    The date of the Tarzan adventures was given in the letter page of one of the Tarzan issues.

    He could certainly return if anyone wanted him to do so.

    During his Tarzan appearances Alhazred's face is consistently swathed in shadow, far more than should be expected just because he is wearing a hood; the Korzar leader Cid even calls Alhazred "Shadowface." It appears the shadows are therefore a manifestation of the supernatural power within him. By the time he reappeared in Marvel Comics Presents the perma-shadow was gone, but we only ever saw his face from the eyebrows down to his bottom lip; the remainder of his face was always hidden by his keffiyeh (hood), agal (head cord) and litham (mouth veil). Despite that, we do see that his eyes are blue in close-ups in Tarzan#21 and MCP I#154 and 155 (so if he is a spirit jumping from host body to host body then either both hosts we saw had blue eyes, or Alhazred had blue eyes and transformed his hosts' eyes to match his); that said, while his eyes are clearly blue on these three occasions and too small to clearly see or uncolored most of his other appearances, they are twice shown as being red in his first appearance in Tarzan#15.
    Though we don't see his hair atop his head, if it matches his eyebrows then he has dark, probably black, hair. - Loki

    In Monsters Unleashed#3, a sorceress in the era of the Depression enabled a man to enter a magic mannikin using spells from the tome of Alhazred. She summoned Satan, who appeared before both of them.
--Per Degaton

    Per Marvel Team-Up I#76 legends said that the Necronomicon was partly derived from the Shiatra Book of the Damned which is another name for the Darkhold.
BTW this was revealed by none other than Dr. Strange and to the site it was pointed out by Per Degaton.

    The editor of Marvel Comics Presents (Richard Ashford or co-editor Michael Kraiger) admitted that readers had "seen his face before" (that is, Alhazred's face; the comment can be found in the letters page of MCP#160). That would suggest that they were acknowledging the Tarzan appearances of Alhazred.
  There was also a boat in a Nightcrawler mini-series issue (Nightcrawler I#3, it was the boat of Kitty and Colossus or Kitty's Fairytale) named Abdul Alhazred.
--Per Degaton & Markus Raymond (the latter went on a journey through Degaton's mind to find the missing pieces to the above comments like issue numbers or names of the people involved)

"http://www.straightdope.com/mailbag/mnecromicon.html

• Yet another Lovecraft reference! One of the recurring plot devices was the "terrible and forbidden" book,
  The Necronomicon, an all-purpose book of demonology, occult lore, and magic, written by "the mad Arab, Abdul Alhazred." Lovecraft first made reference to The Necronomicon in "The Hound" (1922), and earlier to Abdul Alhazred in "The Nameless City" (1921).
• Lovecraft said that he invented the name Abdul Alhazred after reading Lang's Arabian Nights as a child; but elsewhere he said that, as an adult, he asked the family lawyer to make up an Arab name. BTW, the Arabic is wrong: the -ul of Abdul is redundant with the Al of Alhazred. A better rendering would have been Abd-el-Hazred although Joshi calls that "much less charismatic."
• In 1927, Lovecraft wrote the "History of the Necronomicon" as a tongue-in-cheek history of his mythical book. He said he did it to give "a sort of air of verisimilitude." Doubtless also to be sure that all the other writers who were making reference to the Necronomicon would be consistent.
• According to Lovecraft's "History," the Necronomicon was written in the 8th Century AD by the "mad Arab" Alhazred, and was translated into Greek under the title Necronomicon by Theodorus Philetas in AD 950, then into Latin by Olias Wormius in 1228. (The real Wormius--a Danish doctor--lived from 1588 to 1654.) An "imperfect" English translation was supposedly made by Dr. John Dee (1527-1608), an English mathematician and astrologer. And so on. Lovecraft thus created a detailed background for his imaginary book.
• When fans wrote Lovecraft in the 1930s to ask if these books were real, he replied truthfully (as quoted above.) In a 1936 letter, for instance, he says, "I am forced to say that most of them are purely imaginary. There never was any Abdul Alhazred or Necronomicon, for I invented these names myself." "

   On the Darkhold vs Necronomicon: Dr. Strange thought the Necronomicon was copied from the Darkhold (Marvel Team-Up I#76), but the Atlantean Logomancer in Namor: The First Mutant#3 cited legends that both tomes had been copied from writings in R'llyeh (apparently a variant spelling for R'lyeh, where Lovecraft claimed the Great Old One Cthulhu is imprisoned beneath the Pacific waves). Since we've been told that Chthon wrote the Darkhold, this might be considered a contradiction of established continuity, except that (a) the Logomancer did say it was only legend and (b) we were subsequently told that other Great Old Ones lived in R'lyeh (King in Black: Namor#2) and that Chthon was the greatest of the Great Old Ones (Carnage II#14). In terms of Chthon allegedly being a Great Old One when we know he is an Elder God, this might be evidence that the Great Old Ones are some of the Elder Gods who devolved into demons, or, since the Great Old Ones are frequently stated to be non-terrestrial in origins and the Elder Gods were birthed from Earth's energies and hence are decidedly terrestrial, it may be that Chthon joined the Great Old Ones' "pantheon" at some point, the same way Gaea made herself part of several pantheons of Earth's gods. In terms of which writings are derived from which, we know the actual physical pages of the Darkhold were personally inscribed by Chthon (hence why the pages are indestructible), so it ISN'T a copy of the writings in R'llyeh, but Chthon may have also inscribed the same or overlapping mystic texts into the walls of that city, and if the Necronomicon is derived from Chthon's writings, it could have been copied from either - though Alhazred would have had an easier time tracking down the Darkhold to copy from than visiting sunken R'llyeh.. 

    Because of the influence of Lovecraft's writings on modern horror, the Necronomicon has turned up in various novels and films as a homage. Notable among those is the Evil Dead franchise, where it is the book that triggers the outbreak of demonic zombie "Deadites" in each movie; the reason this is more relevant for Marvel than other such homages is because that version of the Necronomicon turned up in Marvel Zombies: Army of Darkness. - Loki

    In addition, Mike Murphy tells me: This particular version of Alhazred hues close to the version that appeared in Marvel's Tarzan comic ( circa issues #15-23, I believe ).
--It took me awhile to get those Tarzan issues, but I finally got them:

• Pellucidar, in Edgar Rice Burroughs' stories, was a world at the center of the Earth, which was bounded 360 degrees by land, the surface of which possessed sufficient gravity to allow normal movement. If these stories are part of the Marvel Universe, I'd consider Pellucidar more likely a pocket dimension, which had a subterranean portal.
• With Tarzan#21, Kraft was replaced by Bill Mantlo, who frequently picked up sagas dropped by others. I'm not certain what Kraft had intended, but during his portion I was thinking, "This is great! This is definitely the same guy--I didn't realize the Tarzan stories were definitely tied to the Marvel Universe." Then Mantlo took over and gave Alhazred's origin, and I thought, "What the frick...!???"
  This character has the name (both Abdul Alhazred and the Mad Arab), the appearance, and the demeanor of the one from Marvel Comics Presents (written some 16 years later). However, the origin of the Tarzan version has no connection to the Lovecraftian version, and instead was a normal guy in the 20th century. What to do, What to do...?
• My thoughts: The Tarzan version is a person possessed by the spirit of the Lovecraftian version. The Lovecraft version did travel to Pellucidar, but died, and his spirit was somehow contained within the crystal by the Mahar. The Tarzan guy was possessed by the Lovecraftian version, but sought to regain his full power and free his spirit from the Mahar crystal. The modern era version could be another person possessed by the spirit of the Lovecraftian version, or could be the original, who eventually escaped from the Mahar crystal in Pellucidar and returned to Earth.
  --This idea is supported by supplemental info provided by Luis Olvao Dantas:
  Abdul was the subject of one of the mind-switches that members of the Great Race of Yith use for studying other times. http://victorian.fortunecity.com/lion/157/trans.htm ("mine immortal essence indwelt the ungainly form of some great cone")
  For details on the Yithians, see "The Shadow Out of Time" or page 106 of the Call of Cthulhu RPG rulesbook.  I quote this rulebook: "The Great Race... will permit... them to meet other victims like themselves, generally from far distant planets or eras. When the time comes to restore the victim to his own body, the Great Race blanks his memory of all that has happened to him while he is trapped in their age.  This blanking is not perfect: the victim may dream of or have nightmares concerning being held by the Great Race."
  Why do I mention this?  Because it may well be of use in the search of an explanation for the link between the two Marvel Abduls. It was within the Yithians' capabilities to clone, time-transport or meddle with the memories of Abdul.  Perhaps they did.
• ...Or, the Tarzan stories are NOT in continuity...I don't like that option.
• ...Or, it's a separate, unrelated character...but they seem WAY too similar for that.
• ...Or, make up your own version.

   A potential minor inconvenience for the 1920s guy to be a host of the spirit of the 8th century Abdul Alhazred is that     "The Nameless City" was first published in the November 1921 issue of the amateur press journal The Wolverine.
--Per Degaton

    The Tarzan stories were brought into continuity in Mystic Arcana: The Book of Marvel Magic in Alhazred's own entry.
--Markus Raymond

   In Monsters Unleashed#3/3 the Witch of the Hills cited Alhazred's book as the source of a spell that invoked the "demon" Yngvi; since Yngvi is actually another name for the Asgardian god Frey, it's unclear whether she (and Alhzared) didn't know this and were actually invoking the god, if there is a demon who has taken to using one of Frey's aliases, or even if there is a version of Frey, perhaps a survivor of a past Ragnarok cycle, who is still around separate from the current incarnation and who has devolved into a demon.

    Wolverine's first encounter with Alhazred takes place prior to him having Adamantium laced into his skeleton, as evidenced by Wolverine not using his claws during their fight. - Loki

CLARIFICATIONS:
Abdul Alhazred has no known connections to:

Hawk

The 1920s Alhazred had a pet hawk that was linked to his life force and obeyed his silent commands (perhaps conveyed telepathically). To make it more lethal, Alhazred shod its claws with iron. It apparently enjoyed feasting on human flesh as it was seen on one occasion to swoop onto the corpse of a slave Alhazred had slain. It accompanied him to Pellucidar, but when Alhazred finally reached the Mahar Crystal his foe Ayesha tried to slay the Mad Arab with a sonic cannon; the blast struck the hawk first, and obliterated it.
