Ubayy ibne-Kaab Radi Allahu anhu narrates
that once the Mushrikin (polytheists) said to
Nabi Sall-Allahu alaihi wasallam:
What is the lineage of your Rabb?"
Thereupon Allah Subhanahu wa Ta-ala,
sent down (Surah Ikhlas):
"Qul Hu Wallahu Ahad.
Lam Yalid walam Yulad.
Walam Yakul-lahu Kufuwan Ahad."
"Say (O Muhammad)!
He is Allah, The One.
Allah, the Self-Sufficient upon Whom all depend.
He does not give birth, nor was He born,
and there is none comparable to Him."
