The word(s) "affair" appears 54 time(s) in 50 verse(s) in Quran in Mohsin Khan translation.

(11) Verily, those who divide their religion and break up into sects (all kinds of religious sects) , you (O Muhammad صلى الله عليه وسلم) have no concern in them in the least. Their affair is only with Allah, Who then will tell them what they used to do.

(12) Surely, your Lord is Allah Who created the heavens and the earth in six Days and then rose over (Istawa ) the Throne (really in a manner that suits His Majesty), disposing the affair of all things. No intercessor (can plead with Him) except after His Leave. That is Allah, your Lord; so worship Him (Alone). Then, will you not remember?

(13) Say (O Muhammad صلى الله عليه وسلم): "Who provides for you from the sky and the earth? Or who owns hearing and sight? And who brings out the living from the dead and brings out the dead from the living? And who disposes the affairs?" They will say: "Allah." Say: "Will you not then be afraid of Allah's punishment (for setting up rivals in worship with Allah)?"

(14) Say: "O you mankind! Now truth (i.e. the Qur'an and Prophet Muhammad صلى الله عليه وسلم) has come to you from your Lord. So whosoever receives guidance, he does so for the good of his own self; and whosoever goes astray, he does so to his own loss; and I am not (set) over you as a Wakil (disposer of affairs to oblige you for guidance)."

(15) So perchance you (Muhammad صلى الله عليه و سلم) may give up a part of what is revealed unto you, and that your breast feels straitened for it because they say, "Why has not a treasure been sent down unto him, or an angel has come with him?" But you are only a warner. And Allah is a Wakil (Disposer of affairs, Trustee, Guardian) over all things.

(16) And to Allah belongs the Ghaib (Unseen) of the heavens and the earth, and to Him return all affairs (for decision). So worship Him (O Muhammad صلى الله عليه و سلم) and put your trust in Him. And your Lord is not unaware of what you (people) do.

(17) So, when they took him away and they all agreed to throw him down to the bottom of the well, (they did so) and We revealed to him: "Indeed, you shall (one day) inform them of this their affair, when they know (you) not."

(18) And he (the man) from Egypt who bought him, said to his wife: "Make his stay comfortable, may be he will profit us or we shall adopt him as a son." Thus did We establish Yusuf (Joseph) in the land, that We might teach him the interpretation of events. And Allah has full power and control over His affairs, but most of men know not.

(19) (The King) said (to the women): "What was your affair when you did seek to seduce Yusuf (Joseph)?" The women said: "Allah forbid! No evil know we against him!" The wife of Al-'Aziz said: "Now the truth is manifest (to all); it was I who sought to seduce him, and he is surely of the truthful."

(20) Allah is He Who raised the heavens without any pillars that you can see. Then, He rose above (Istawa) the Throne (really in a manner that suits His Majesty). He has subjected the sun and the moon (to continue going round), each running (its course) for a term appointed. He manages and regulates all affairs; He explains the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) in detail, that you may believe with certainty in the meeting with your Lord.
