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

(61) For any whom Allah leaves astray, there is no protector thereafter. And thou wilt see the Wrong-doers, when in sight of the Penalty, Say: "Is there any way (to effect) a return?"

(62) And also adornments of gold. But all this were nothing but conveniences of the present life: The Hereafter, in the sight of thy Lord is for the Righteous.

(63) They will be of no use to thee in the sight of Allah: it is only Wrong-doers (that stand as) protectors, one to another: but Allah is the Protector of the Righteous.

(64) Then seest thou such a one as takes as his god his own vain desire? Allah has, knowing (him as such), left him astray, and sealed his hearing and his heart (and understanding), and put a cover on his sight. Who, then, will guide him after Allah (has withdrawn Guidance)? Will ye not then receive admonition?

(65) And We had firmly established them in a (prosperity and) power which We have not given to you (ye Quraish!) and We had endowed them with (faculties of) hearing, seeing, heart and intellect: but of no profit to them were their (faculties of) hearing, sight, and heart and intellect, when they went on rejecting the Signs of Allah; and they were (completely) encircled by that which they used to mock at!

(66) Such are the men whom Allah has cursed for He has made them deaf and blinded their sight.

(67) That He may admit the men and women who believe, to Gardens beneath which rivers flow, to dwell therein for aye, and remove their ills from them;- and that is, in the sight of Allah, the highest achievement (for man),-

(68) O mankind! We created you from a single (pair) of a male and a female, and made you into nations and tribes, that ye may know each other (not that ye may despise (each other). Verily the most honoured of you in the sight of Allah is (he who is) the most righteous of you. And Allah has full knowledge and is well acquainted (with all things).

(69) (It will be said:) "Thou wast heedless of this; now have We removed thy veil, and sharp is thy sight this Day!"

(70) (His) sight never swerved, nor did it go wrong!
