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

(61) And on the Day that the Unbelievers will be placed before the Fire, (they will be asked,) "Is this not the Truth?" they will say, "yea, by our Lord!" (One will say:) "Then taste ye the Penalty, for that ye were wont to deny (Truth)!"

(62) yea, to Allah belongs all that is in the heavens and on earth: so that He rewards those who do evil, according to their deeds, and He rewards those who do good, with what is best.

(63) yea, how (terrible) was My Penalty and My Warning!

(64) Say: "yea, those of old and those of later times,

(65) O ye who believe! Fear Allah, and let every soul look to what (provision) He has sent forth for the morrow. yea, fear Allah: for Allah is well-acquainted with (all) that ye do.

(66) When the Hypocrites come to thee, they say, "We bear witness that thou art indeed the Messenger of Allah." yea, Allah knoweth that thou art indeed His Messenger, and Allah beareth witness that the Hypocrites are indeed liars.

(67) He knows what is in the heavens and on earth; and He knows what ye conceal and what ye reveal: yea, Allah knows well the (secrets) of (all) hearts.

(68) The Unbelievers think that they will not be raised up (for Judgment). Say: "yea, By my Lord, Ye shall surely be raised up: then shall ye be told (the truth) of all that ye did. And that is easy for Allah."

(69) The angels and the spirit ascend unto him in a Day the measure whereof is (as) fifty thousand years:

(70) Thy Lord doth know that thou standest forth (to prayer) nigh two-thirds of the night, or half the night, or a third of the night, and so doth a party of those with thee. But Allah doth appoint night and day in due measure He knoweth that ye are unable to keep count thereof. So He hath turned to you (in mercy): read ye, therefore, of the Qur'an as much as may be easy for you. He knoweth that there may be (some) among you in ill-health; others travelling through the land, seeking of Allah's bounty; yet others fighting in Allah's Cause, read ye, therefore, as much of the Qur'an as may be easy (for you); and establish regular Prayer and give regular Charity; and loan to Allah a Beautiful Loan. And whatever good ye send forth for your souls ye shall find it in Allah's Presence,- yea, better and greater, in Reward and seek ye the Grace of Allah: for Allah is Oft-Forgiving, Most Merciful.
