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

(241) That is the commandment of Allah which He revealeth unto you. And whoso keepeth his duty to Allah, He will remit from him his evil deeds and magnify reward for him.

(242) Lodge them where ye dwell, according to your wealth, and harass them not so as to straiten life for them. And if they are with child, then spend for them till they bring forth their burden. Then, if they give suck for you, give them their due payment and consult together in kindness; but if ye make difficulties for one another, then let some other woman give suck for him (the father of the child).

(243) let him who hath abundance spend of his abundance, and he whose provision is measured, let him spend of that which Allah hath given him. Allah asketh naught of any soul save that which He hath given it. Allah will vouchsafe, after hardship, ease.

(244) When they are flung therein they hear its roaring as it boileth up,

(245) Or have ye taken security from Him Who is in the heaven that He will not let loose on you a hurricane? But ye shall know the manner of My warning.

(246) What aileth you? How foolishly ye judge!

(247) Or have they other gods? Then let them bring their other gods if they are truthful

(248) On the day when it befalleth in earnest, and they are ordered to prostrate themselves but are not able,

(249) It calleth him who turned and fled (from truth),

(250) Fretful when evil befalleth him
