Was the Prophet Muhammad (SAW) influenced by a satan called abyad?
(A brother watched a video wherein a Christian read a narration from Tafsir Qurtubi that appeared to say a devil called abyad frequented the prophet saw. According to Arabian folklore this devil is the lord of Monday. The speaker in question then quoted a biography of the prophet SAW called the sealed nectar wherein it says the revelation began on a monday, trying to impute that thsi revelation must have come from this devil abyad. Since this was over a whatsapp conversation and not a formal question, the answer was brief.)
In essence there are two main points to note that debunk the entire video. The first is that there is no authentic narration regarding abyad. The author, qurtubi, mentions this himself although the person in the video obviously left that out. The second is that there is huge difference of opinion as to when the prophet SAW actually began receiving revelation. Monday is just one view. In the end there appears to be no substance to this claim.
As to why this narration appeared in the books of tafsir in the first place, we should understand that some tafsirs were attempting to gather every single narration possible with the chain and present such that a person with knowledge of chains of narration could make out which one is authentic and which isn’t. Secondly, many of them mentioned it in order to rebut it.
