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

(91) O ye who believe! Fight those of the disbelievers who are near to you, and let them find harshness in you, and know that Allah is with those who keep their duty (unto Him).

(92) He it is Who appointed the sun a splendour and the moon a light, and measured for her stages, that ye might know the number of the years, and the reckoning. Allah created not (all) that save in truth. He detaileth the revelations for people who have knowledge.

(93) The similitude of the life of the world is only as water which We send down from the sky, then the earth's growth of that which men and cattle eat mingleth with it till, when the earth hath taken on her ornaments and is embellished, and her people deem that they are masters of her, Our commandment cometh by night or by day and We make it as reaped corn as if it had not flourished yesterday. Thus do we expound the revelations for people who reflect.

(94) Say: Is there of your partners (whom ye ascribe unto Allah) one that leadeth to the Truth? Say: Allah leadeth to the Truth. Is He Who leadeth to the Truth more deserving that He should be followed, or he who findeth not the way unless he (himself) be guided. What aileth you? How judge ye?

(95) Whether We let thee (O Muhammad) behold something of that which We promise them or (whether We) cause thee to die, still unto Us is their return, and Allah, moreover, is Witness over what they do.

(96) Say: I have no power to hurt or benefit myself, save that which Allah willeth. For every nation there is an appointed time. When their time cometh, then they cannot put it off an hour, nor hasten (it).

(97) Say: In the bounty of Allah and in His mercy: therein let them rejoice. It is better than what they hoard.

(98) And let not their speech grieve thee (O Muhammad). Lo! power belongeth wholly to Allah. He is the Hearer, the Knower.

(99) Recite unto them the story of Noah, when he told his people: O my people! If my sojourn (here) and my reminding you by Allah's revelations are an offence unto you, in Allah have I put my trust, so decide upon your course of action you and your partners. let not your course of action be in doubt for you. Then have at me, give me no respite.

(100) (The messengers) said: O Lot! Lo! we are messengers of thy Lord; they shall not reach thee. So travel with thy people in a part of the night, and let not one of you turn round - (all) save thy wife. Lo! that which smiteth them will smite her (also). Lo! their tryst is (for) the morning. Is not the morning nigh?
