The word(s) "affair" appears 10 time(s) in 9 verse(s) in Quran in Muhammad Pickthal translation.

(1) Upon the world and the Hereafter. And they question thee concerning orphans. Say: To improve their lot is best. And if ye mingle your affairs with theirs, then (they are) your brothers. Allah knoweth him who spoileth from him who improveth. Had Allah willed He could have overburdened you. Allah is Mighty, Wise.

(2) Those who swallow usury cannot rise up save as he ariseth whom the devil hath prostrated by (his) touch. That is because they say: Trade is just like usury; whereas Allah permitteth trading and forbiddeth usury. He unto whom an admonition from his Lord cometh, and (he) refraineth (in obedience thereto), he shall keep (the profits of) that which is past, and his affair (henceforth) is with Allah. As for him who returneth (to usury) - Such are rightful owners of the Fire. They will abide therein.

(3) It was by the mercy of Allah that thou wast lenient with them (O Muhammad), for if thou hadst been stern and fierce of heart they would have dispersed from round about thee. So pardon them and ask forgiveness for them and consult with them upon the conduct of affairs. And when thou art resolved, then put thy trust in Allah. Lo! Allah loveth those who put their trust (in Him).

(4) When Allah showed them unto thee (O Muhammad) in thy dream as few in number, and if He had shown them to thee as many, ye (Muslims) would have faltered and would have quarrelled over the affair. But Allah saved (you). Lo! He knoweth what is in the breasts (of men).

(5) They only are the true believers who believe in Allah and His messenger and, when they are with him on some common errand, go not away until they have asked leave of him. Lo! those who ask leave of thee, those are they who believe in Allah and His messenger. So, if they ask thy leave for some affair of theirs, give leave to whom thou wilt of them, and ask for them forgiveness of Allah. Lo! Allah is Forgiving, Merciful.

(6) And it becometh not a believing man or a believing woman, when Allah and His messenger have decided an affair (for them), that they should (after that) claim any say in their affair; and whoso is rebellious to Allah and His messenger, he verily goeth astray in error manifest.

(7) Say: Whatever reward I might have asked of you is yours. My reward is the affair of Allah only. He is Witness over all things.

(8) And those who answer the call of their Lord and establish worship, and whose affairs are a matter of counsel, and who spend of what We have bestowed on them,

(9) The guerdon of an ill-deed is an ill the like thereof. But whosoever pardoneth and amendeth, his wage is the affair of Allah. Lo! He loveth not wrong-doers.
