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

(61) Say: "O men! I am sent unto you all, as the Messenger of Allah, to Whom belongeth the dominion of the heavens and the earth: there is no god but He: it is He That giveth both life and death. So believe in Allah and His Messenger, the Unlettered Prophet, who believeth in Allah and His words: follow him that (so) ye may be guided."

(62) Say: "I have no power over any good or harm to myself except as Allah willeth. If I had knowledge of the unseen, I should have multiplied all good, and no evil should have touched me: I am but a warner, and a bringer of glad tidings to those who have faith."

(63) Verily those whom ye call upon besides Allah are servants like unto you: Call upon them, and let them listen to your prayer, if ye are (indeed) truthful!

(64) O ye who believe! give your response to Allah and His Messenger, when He calleth you to that which will give you life; and know that Allah cometh in between a man and his heart, and that it is He to Whom ye shall (all) be gathered.

(65) let not the unbelievers think that they can get the better (of the godly): they will never frustrate (them).

(66) O ye who believe! Truly the Pagans are unclean; so let them not, after this year of theirs, approach the Sacred Mosque. And if ye fear poverty, soon will Allah enrich you, if He wills, out of His bounty, for Allah is All-knowing, All-wise.

(67) Say: "Nothing will happen to us except what Allah has decreed for us: He is our protector": and on Allah let the Believers put their trust.

(68) let not their wealth nor their (following in) sons dazzle thee: in reality Allah's plan is to punish them with these things in this life, and that their souls may perish in their (very) denial of Allah.

(69) let them laugh a little: much will they weep: a recompense for the (evil) that they do.

(70) Nor let their wealth nor their (following in) sons dazzle thee: Allah's plan is to punish them with these things in this world, and that their souls may perish in their (very) denial of Allah.
