The word(s) "let" appears 245 time(s) in 205 verse(s) in Quran in Abdullah Yusuf Ali translation.

(101) Thus did We make their case known to the people, that they might know that the promise of Allah is true, and that there can be no doubt about the Hour of Judgment. Behold, they dispute among themselves as to their affair. (Some) said, "Construct a building over them": Their Lord knows best about them: those who prevailed over their affair said, "let us surely build a place of worship over them."

(102) And keep thy soul content with those who call on their Lord morning and evening, seeking His Face; and let not thine eyes pass beyond them, seeking the pomp and glitter of this Life; nor obey any whose heart We have permitted to neglect the remembrance of Us, one who follows his own desires, whose case has gone beyond all bounds.

(103) Say, "The truth is from your Lord": let him who will believe, and let him who will, reject (it): for the wrong-doers We have prepared a Fire whose (smoke and flames), like the walls and roof of a tent, will hem them in: if they implore relief they will be granted water like melted brass, that will scald their faces, how dreadful the drink! How uncomfortable a couch to recline on!

(104) For them will be Gardens of Eternity; beneath them rivers will flow; they will be adorned therein with bracelets of gold, and they will wear green garments of fine silk and heavy brocade: They will recline therein on raised thrones. How good the recompense! How beautiful a couch to recline on!

(105) "And how canst thou have patience about things about which thy understanding is not complete?"

(106) (He left them) as they were: We completely understood what was before him.

(107) Say: "I am but a man like yourselves, (but) the inspiration has come to me, that your Allah is one Allah: whoever expects to meet his Lord, let him work righteousness, and, in the worship of his Lord, admit no one as partner.

(108) But (a voice) cried to her from beneath the (palm-tree): "Grieve not! for thy Lord hath provided a rivulet beneath thee;

(109) "And shake towards thyself the trunk of the palm-tree: It will let fall fresh ripe dates upon thee.

(110) "Therefore let not such as believe not therein but follow their own lusts, divert thee therefrom, lest thou perish!"..
