Ka'b ibn Lu'ayy

One of the grandees of pre-Islamic Quraysh; he gathered his people on Fridays — hence 'the day of Ka'b' — telling them what he had read in the earlier scriptures about a prophet who would come from his loins, and bidding them follow him ^{1 2}.

He would say to the gathered Quraysh: hear, understand, retain and obey, and you shall prosper — for God will honour you with a man who comes from my loins whose affair grows great and whose name is raised high ¹.

Ka'b ibn Lu'ayy is one of the Prophet ﷺ's ancestors in the part of the lineage the genealogists agree on, from Adnan down to Abdullah ibn Abd al-Muttalib.
