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

(71) That (the fruit of) his striving will soon come in sight:

(72) Turnest thou not thy sight towards those who were forbidden secret counsels yet revert to that which they were forbidden (to do)? And they hold secret counsels among themselves for iniquity and hostility, and disobedience to the Messenger. And when they come to thee, they salute thee, not as Allah salutes thee, (but in crooked ways): And they say to themselves, "Why does not Allah punish us for our words?" Enough for them is Hell: In it will they burn, and evil is that destination!

(73) Grievously odious is it in the sight of Allah that ye say that which ye do not.

(74) Though they will be put in sight of each other,- the sinner's desire will be: Would that he could redeem himself from the Penalty of that Day by (sacrificing) his children,

(75) At length, when the sight is dazed,

(76) Verily We created Man from a drop of mingled sperm, in order to try him: So We gave him (the gifts), of Hearing and sight.

(77) On Thrones (of Dignity) will they command a sight (of all things):

(78) On Thrones (of Dignity) they will command (a sight) (of all things).

(79) Again, ye shall see it with certainty of sight!
