(15) Say: Shall I choose for a protecting friend other than Allah, the Originator of the heavens and the earth, Who feedeth and is never fed? Say: I am ordered to be the first to surrender (unto Him). And be not thou (O Muhammad) of the idolaters.

(18) O Children of Adam! Let not Satan seduce you as he caused your (first) parents to go forth from the Garden and tore off from them their robe (of innocence) that he might manifest their shame to them.

(19) And Moses chose of his people seventy men for Our appointed tryst and, when the trembling came on them, he said: My Lord! If Thou hadst willed Thou hadst destroyed them long before, and me with them. Wilt thou destroy us for that which the ignorant among us did? It is but Thy trial (of us). Thou sendest whom Thou wilt astray and guidest whom Thou wilt: Thou art our Protecting friend, therefore forgive us and have mercy on us, Thou, the Best of all who show forgiveness.

(20) Lo! my Protecting friend is Allah Who revealeth the Scripture. He befriendeth the righteous.
