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

(21) Have they feet wherewith they walk? Or have they hands wherewith they hold? Or have they eyes wherewith they see? Or have they ears wherewith they hear? Say (O Muhammad صلى الله عليه وسلم): "Call your (so-called) partners (of Allah) and then plot against me, and give me no respite!

(22) And (remember) when you met (the army of the disbelievers on the Day of the battle of Badr), He showed them to you as few in your eyes and He made you appear as few in their eyes, so that Allah might accomplish a matter already ordained (in His Knowledge), and to Allah return all matters (for decision).

(23) Nor (is there blame) on those who came to you to be provided with mounts, when you said: "I can find no mounts for you," they turned back, while their eyes overflowing with tears of grief that they could not find anything to spend (for Jihad).

(24) Verily, the likeness of (this) worldly life is as the water (rain) which We send down from the sky; so by it arises the intermingled produce of the earth of which men and cattle eat: until when the earth is clad in its adornments and is beautified, and its people think that they have all the powers of disposal over it, Our Command reaches it by night or by day and We make it like a clean-mown harvest, as if it had not flourished yesterday! Thus do We explain the Ayat (proofs, evidence, verses, lessons, signs, revelations, laws, etc.) in detail for the people who reflect.

(25) And they ask you (O Muhammad صلى الله عليه وسلم) to inform them (saying): "Is it true (i.e. the torment and the establishment of the Hour - the Day of Resurrection)?" Say: "yes! By my Lord! It is the very truth! and you cannot escape it!"

(26) "And I do not say to you that with me are the Treasures of Allah, nor that I know the Ghaib (Unseen), nor do I say I am an angel, and I do not say of those whom your eyes look down upon that Allah will not bestow any good on them. Allah knows what is in their inner-selves (as regards belief, etc.). In that case, I should, indeed be one of the Zalimun (wrong-doers, oppressors)."

(27) "And construct the ship under Our Eyes and with Our Revelation, and call not upon Me on behalf of those who did wrong; they are surely to be drowned."

(28) Consider not that Allah is unaware of that which the Zalimun (polytheists, wrong-doers) do, but He gives them respite up to a Day when the eyes will stare in horror.

(29) They would surely say (in the evening): "Our eyes have been (as if) dazzled (we have not seen any angel or heaven). Nay, we are a people bewitched."

(30) Look not with your eyes ambitiously at what We have bestowed on certain classes of them (the disbelievers), nor grieve over them. And lower your wings for the believers (be courteous to the fellow-believers).
