As per reddiquette, I am obligated to start this off by informing you that I'm cross-posting from /r/AskHistory and /r/Mythology. Though the title has been slightly condensed since I really need a very high chance of getting this answered for the sake of my book (mentioned below) and neither thread has procured a response as of yet. Original text follows:
I have been trying to do research into this for a novel I'm writing and the following four deities are listed most often; Hubal, Al-ʻUzzā, Al-Lāt, and Manāt.
However, those four do not satisfy the specific things I need for the purposes of the narrative I'm writing. Digging ever deeper into the bowls of the web, I seemed to repeatedly find blog posts and forum posts that mention more obscure deities. Do either of the lists linked to above seem valid based on other sources you've seen before? (F.Y.I. - For the forum post link, scroll all the way down to the bottom of the page you're directed to for the list I'm referring to)
Overall, I am mainly concerned about the authenticity of this deity called Awf. These two links claim that he's often represented as an eagle, considered a divine ancestor of the tribe, and presides over divination by a method called zajr.
Hey! So I looked mostly into Awf and Zajr.
al-Zajr, as described by Toufiq Fahd in La Divination Arabe (qtd. in Signs, Omens, and Semiological Regimes in Early Islamic Texts from the Harvard Center on Hellenic Studies) is:
a method of divination which essentially consisted of throwing a stone at a bird and shouting at it. A bird which flew away to right of the thrower (zājir) was taken to be a favorable portent (tafāʾala bi-hi), while the leftward-flying bird was taken as an unfavorable one (taṭayyara). Testimony for the antiquity of this practice is found in a verse of Labīd, which also indicates that al-zajr was practiced by women. [46] This is supported by a ḥadī th related by one Umm Karz, who said: “I went before the Prophet and heard him say: ‘Let the birds stay in their places’ (var. ‘in their nests’).” Asked about the meaning of this ḥadī th, al-Shāfiʿī (d. 204/820) said: “The Arabs were masters at the technique of inducing birds to fly. When one of them wished to make a journey, he would exit his dwelling until he came upon some perching birds, which he would then cause to fly away. If they flew off to the right, he would continue on his journey; but if they flew off to the left, then he would go back home.”
From here, one can see the link between Awf (who supposedly controls the flights of birds) and Zajr. However, when I tried to find some more concrete evidence on Awf himself, I came up a little short. I started with the broad book Arabia and the Arabs by Robert Hoyland, which has a decent overview of pre-Islamic religion but did not find mention of him. He also does not appear within either Michael Jordan's Dictionary of Gods and Goddesses, or within The Routledge Dictionary of Gods, Goddesses, Devils & Demons. There are 41 other Arabian gods listed in the first, and 45 in the second, so I would be hesitant to say that Awf's absence is due to the dictionaries being incomplete. Finally, I looked through a good 80% of the links at the end of the first blog post (at least those available online) and searched for "awf", "auf", "divination" and "zajr" and didn't come up with any hits.
The other gods/goddesses that you have mentioned - Hubal, Al-ʻUzzā, Al-Lāt, and Manāt - are all attested for and I have found them mentioned many times in academic texts.
I am sorry that I can't be of more help. The lack of reliable information on many of these ancient gods is a huge burden for research, and if you were to believe every website online you would have to believe the Ka'ba is from outer-space, a Hindu shrine, and a satanic temple! If you have any other questions, I will hopefully have some more luck.
Also, if you don't mind me asking, what exactly is your book about?
EDIT: I'd also just like to say that Awf may still exist. There were roughly 360 deities in the Ka'ba and Hoyland says we have the names of at least 100 of them. I merely couldn't find such a list in English within the couple of hours I put into this.
