The word(s) "yea" appears 79 time(s) in 75 verse(s) in Quran in Abdullah Yusuf Ali translation.

(51) He rules (all) affairs from the heavens to the earth: in the end will (all affairs) go up to Him, on a Day, the space whereof will be (as) a thousand years of your reckoning.

(52) "Is not He Who created the heavens and the earth able to create the like thereof?" - yea, indeed! for He is the Creator Supreme, of skill and knowledge (infinite)!

(53) Say thou: "yea, and ye shall then be humiliated (on account of your evil)."

(54) yea, such! but - for the wrong-doers will be an evil place of (Final) Return!-

(55) yea, such! - then shall they taste it,- a boiling fluid, and a fluid dark, murky, intensely cold!-

(56) (yea, the same that) has made for you the earth (like a carpet) spread out, and has made for you roads (and channels) therein, in order that ye may find guidance (on the way);

(57) yea, I have given the good things of this life to these (men) and their fathers, until the Truth has come to them, and a messenger making things clear.

(58) And they say, "Are our gods best, or he?" This they set forth to thee, only by way of disputation: yea, they are a contentious people.

(59) We have enjoined on man kindness to his parents: In pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says, "O my Lord! Grant me that I may be grateful for Thy favour which Thou has bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam."

(60) See they not that Allah, Who created the heavens and the earth, and never wearied with their creation, is able to give life to the dead? yea, verily He has power over all things.
