The word(s) "yes" appears 93 time(s) in 91 verse(s) in Quran in Mohsin Khan translation.

(51) Being miserly towards you (as regards help and aid in Allah's Cause). Then when fear comes, you will see them looking to you, their eyes revolving like (those of) one over whom hovers death; but when the fear departs, they will smite you with sharp tongues, miserly towards (spending anything in any) good (and only covetous of booty and wealth). Such have not believed. Therefore Allah makes their deeds fruitless and that is ever easy for Allah.

(52) O Prophet! Tell your wives and your daughters and the women of the believers to draw their cloaks (veils) all over their bodies (i.e. screen themselves completely except the eyes or one eye to see the way). That will be better, that they should be known (as free respectable women) so as not to be annoyed. And Allah is Ever Oft-Forgiving, Most Merciful.

(53) Those who disbelieve say: "The Hour will not come to us." Say: "yes, by my Lord, the All-Knower of the Unseen, it will come to you; not even the weight of an atom (or a small ant) or less than that or greater escapes His Knowledge in the heavens or in the earth but it is in a Clear Book (Al-Lauh Al-Mahfuz).

(54) And if it had been Our Will, We would surely have wiped out (blinded) their eyes, so that they would struggle for the Path, how then would they see?

(55) Is not He Who created the heavens and the earth, Able to create the like of them? yes, indeed! He is the All-Knowing Supreme Creator.

(56) Say (O Muhammad صلى الله عليه وسلم): "yes, and you shall then be humiliated."

(57) And beside them will be Qasirat-at-Tarf [chaste females (wives), restraining their glances (desiring none except their husbands)], with wide and beautiful eyes.

(58) Did we take them as an object of mockery, or have (our) eyes failed to perceive them?"

(59) yes! Verily, there came to you My Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) and you denied them, and were proud and were among the disbelievers.

(60) And those who disbelieved will be driven to Hell in groups till, when they reach it, the gates thereof will be opened (suddenly like a prison at the arrival of the prisoners). And its keepers will say, "Did not the Messengers come to you from yourselves, reciting to you the Verses of your Lord, and warning you of the Meeting of this Day of yours?" They will say: "yes, but the Word of torment has been justified against the disbelievers!"
