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

(81) And let not those who disbelieve suppose that they can outstrip (Allah's Purpose). Lo! they cannot escape.

(82) O ye who believe! The idolaters only are unclean. So let them not come near the Inviolable Place of Worship after this their year. If ye fear poverty (from the loss of their merchandise) Allah shall preserve you of His bounty if He will. Lo! Allah is Knower, Wise.

(83) O ye who believe! What aileth you that when it is said unto you: Go forth in the way of Allah, ye are bowed down to the ground with heaviness. Take ye pleasure in the life of the world rather than in the Hereafter? The comfort of the life of the world is but little in the Hereafter.

(84) If good befalleth thee (O Muhammad) it afflicteth them, and if calamity befalleth thee, they say: We took precaution, and they turn away well pleased.

(85) Say: Naught befalleth us save that which Allah hath decreed for us. He is our Protecting Friend. In Allah let believers put their trust!

(86) So let not their riches nor their children please thee (O Muhammad). Allah thereby intendeth but to punish them in the life of the world and that their souls shall pass away while they are disbelievers.

(87) Then let them laugh a little: they will weep much, as the reward of what they used to earn.

(88) let not their wealth nor their children please thee! Allah purposeth only to punish them thereby in the world, and that their souls shall pass away while they are disbelievers.

(89) They will swear by Allah unto you, when ye return unto them, that ye may let them be. let them be, for lo! they are unclean, and their abode is hell as the reward for what they used to earn.

(90) Lo! Allah hath bought from the believers their lives and their wealth because the Garden will be theirs: they shall fight in the way of Allah and shall slay and be slain. It is a promise which is binding on Him in the Torah and the Gospel and the Qur'an. Who fulfilleth His covenant better than Allah? Rejoice then in your bargain that ye have made, for that is the supreme triumph.
