The word(s) "let" appears 320 time(s) in 279 verse(s) in Quran in Muhammad Pickthal translation.

(171) He said: Lo! I fain would marry thee to one of these two daughters of mine on condition that thou hirest thyself to me for (the term of) eight pilgrimages. Then if thou completest ten it will be of thine own accord, for I would not make it hard for thee. Allah willing, thou wilt find me of the righteous.

(172) Thy Lord bringeth to pass what He willeth and chooseth. They have never any choice. Glorified be Allah and Exalted above all that they associate (with Him)!

(173) And let them not divert thee from the revelations of Allah after they have been sent down unto thee; but call (mankind) unto thy Lord, and be not of those who ascribe partners (unto Him).

(174) Whoso looketh forward to the meeting with Allah (let him know that) Allah's reckoning is surely nigh, and He is the Hearer, the Knower.

(175) It is a promise of Allah. Allah faileth not His promise, but most of mankind know not.

(176) And of His signs is this: The heavens and the earth stand fast by His command, and afterward, when He calleth you, lo! from the earth ye will emerge.

(177) So have patience (O Muhammad)! Allah's promise is the very truth, and let not those who have no certainty make thee impatient.

(178) And whosoever disbelieveth, let not his disbelief afflict thee (O Muhammad). Unto Us is their return, and We shall tell them what they did. Lo! Allah is Aware of what is in the breasts (of men).

(179) O mankind! Keep your duty to your Lord and fear a Day when the parent will not be able to avail the child in aught, nor the child to avail the parent. Lo! Allah's promise is the very truth. let not the life of the world beguile you, nor let the deceiver beguile you, in regard to Allah.

(180) Those who disbelieve say: Shall we show you a man who will tell you (that) when ye have become dispersed in dust with most complete dispersal still, even then, ye will be created anew?
