Surat Az-Zukhruf (The Ornaments of Gold) - سورة الزخرف

: And those whom they invoke instead of Him have no power of intercession; except those who bear witness to the truth (i.e. believed in the Oneness of Allah, and obeyed His Orders), and they know (the facts about the Oneness of Allah).

: And if you ask them who created them, they will surely say: "Allah". How then are they turned away (from the worship of Allah, Who created them)?

: (Allah has knowledge) of (Prophet Muhammad's) saying: "O my Lord! Verily, these are a people who believe not!"

: So turn away from them (O Muhammad SAW), and say: Salam (peace)! But they will come to know.
