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

(181) No intercession availeth with Him save for him whom He permitteth. Yet, when fear is banished from their hearts, they say: What was it that your Lord said? They say: The Truth. And He is the Sublime, the Great.

(182) Say: Lo! my Lord hurleth the truth. (He is) the Knower of Things Hidden.

(183) O mankind! Lo! the promise of Allah is true. So let not the life of the world beguile you, and let not the (avowed) beguiler beguile you with regard to Allah.

(184) Is he, the evil of whose deeds is made fairseeming unto him so that he deemeth it good, (other than Satan's dupe)? Allah verily sendeth whom He will astray, and guideth whom He will; so let not thy soul expire in sighings for them. Lo! Allah is Aware of what they do!

(185) Gardens of Eden! They enter them wearing armlets of gold and pearl and their raiment therein is silk.

(186) But as for those who disbelieve, for them is fire of hell; it taketh not complete effect upon them so that they can die, nor is its torment lightened for them. Thus We punish every ingrate.

(187) So let not their speech grieve thee (O Muhammad). Lo! We know what they conceal and what proclaim.

(188) What aileth you that ye help not one another?

(189) For the like of this, then, let the workers work.

(190) What aileth you that ye speak not?
