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

(171) One Day will the Hypocrites- men and women - say to the Believers: "Wait for us! let us borrow (a Light) from your Light!" It will be said: "Turn ye back to your rear! then seek a Light (where ye can)!" So a wall will be put up betwixt them, with a gate therein. Within it will be Mercy throughout, and without it, all alongside, will be (Wrath and) Punishment!

(172) Secret counsels are only (inspired) by the Evil One, in order that he may cause grief to the Believers; but he cannot harm them in the least, except as Allah permits; and on Allah let the Believers put their trust.

(173) Whatever is in the heavens and on earth, let it declare the Praises and Glory of Allah: for He is the Exalted in Might, the Wise.

(174) 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.

(175) O ye who believe! When there come to you believing women refugees, examine (and test) them: Allah knows best as to their Faith: if ye ascertain that they are Believers, then send them not back to the Unbelievers. They are not lawful (wives) for the Unbelievers, nor are the (Unbelievers) lawful (husbands) for them. But pay the Unbelievers what they have spent (on their dower), and there will be no blame on you if ye marry them on payment of their dower to them. But hold not to the guardianship of unbelieving women: ask for what ye have spent on their dowers, and let the (Unbelievers) ask for what they have spent (on the dowers of women who come over to you). Such is the command of Allah: He judges (with justice) between you. And Allah is Full of Knowledge and Wisdom.

(176) Whatever is in the heavens and on earth, let it declare the Praises and Glory of Allah: for He is the Exalted in Might, the Wise.

(177) And remember, Moses said to his people: "O my people! why do ye vex and insult me, though ye know that I am the messenger of Allah (sent) to you?" Then when they went wrong, Allah let their hearts go wrong. For Allah guides not those who are rebellious transgressors.

(178) Their intention is to extinguish Allah's Light (by blowing) with their mouths: But Allah will complete (the revelation of) His Light, even though the Unbelievers may detest (it).

(179) It is He Who has sent amongst the Unlettered a messenger from among themselves, to rehearse to them His Signs, to sanctify them, and to instruct them in Scripture and Wisdom,- although they had been, before, in manifest error;-

(180) O ye who believe! let not your riches or your children divert you from the remembrance of Allah. If any act thus, the loss is their own.
