The word(s) "let" appears 241 time(s) in 215 verse(s) in Quran in Mohsin Khan translation.

(51) And We wrote for him on the Tablets the lesson to be drawn from all things and the explanation for all things (and said): Hold unto these with firmness, and enjoin your people to take the better therein. I shall show you the home of Al-Fasiqun (the rebellious, disobedient to Allah).

(52) And when Musa (Moses) returned to his people, angry and grieved, he said: "What an evil thing is that which you have done (i.e. worshipping the calf) during my absence. Did you hasten and go ahead as regards the matter of your Lord (you left His worship)?" And he threw down the Tablets and seized his brother by (the hair of) his head and dragged him towards him. Harun (Aaron) said: "O son of my mother! Indeed the people judged me weak and were about to kill me, so make not the enemies rejoice over me, nor put me amongst the people who are Zalimun (wrong-doers)."

(53) And when the anger of Musa (Moses) was calmed down, he took up the Tablets; and in their inscription was guidance and mercy for those who fear their Lord.

(54) Whomsoever Allah sends astray, none can guide him; and He lets them wander blindly in their transgressions.

(55) Verily, those whom you call upon besides Allah are slaves like you. So call upon them and let them answer you if you are truthful.

(56) And let not those who disbelieve think that they can outstrip (escape from the punishment). Verily, they will never be able to save themselves (from Allah's Punishment).

(57) O you who believe (in Allah's Oneness and in His Messenger Muhammad صلى الله عليه وسلم)! Verily, the Mushrikun (polytheists, pagans, idolaters, disbelievers in the Oneness of Allah, and in the Message of Muhammad صلى الله عليه وسلم) are Najasun (impure). So let them not come near Al-Masjidal-Haram (at Makkah) after this year; and if you fear poverty, Allah will enrich you if He wills, out of His Bounty. Surely, Allah is All-Knowing, All-Wise.

(58) Say: "Nothing shall ever happen to us except what Allah has ordained for us. He is our Maula (Lord, Helper and Protector)." And in Allah let the believers put their trust.

(59) So let not their wealth nor their children amaze you (O Muhammad صلى الله عليه وسلم); in reality Allah's Plan is to punish them with these things in the life of this world, and that their souls shall depart (die) while they are disbelievers.

(60) So let them laugh a little and (they will) cry much as a recompense of what they used to earn (by committing sins).
