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

(201) A plight like that of Noah's folk, and A'ad and Thamud, and those after them, and Allah willeth no injustice for (His) slaves.

(202) And, O my people! What aileth me that I call you unto deliverance when ye call me unto the Fire?

(203) The day when their excuse availeth not the evil-doers, and theirs is the curse, and theirs the ill abode.

(204) Then have patience (O Muhammad). Lo! the promise of Allah is true. And whether we let thee see a part of that which We promise them, or (whether) We cause thee to die, still unto Us they will be brought back.

(205) Therefor We let loose on them a raging wind in evil days, that We might make them taste the torment of disgrace in the life of the world. And verily the doom of the Hereafter will be more shameful, and they will not be helped.

(206) And of His portents (is this): that thou seest the earth lowly, but when We send down water thereon it thrilleth and groweth. Lo! He Who quickeneth it is verily the Quickener of the Dead. Lo! He is Able to do all things.

(207) Unto Him is referred (all) knowledge of the Hour. And no fruits burst forth from their sheaths, and no female carrieth or bringeth forth but with His knowledge. And on the day when He calleth unto them: Where are now My partners? they will say: We confess unto Thee, not one of us is a witness (for them).

(208) And if Allah were to enlarge the provision for His slaves they would surely rebel in the earth, but He sendeth down by measure as He willeth. Lo! He is Informed, a Seer of His bondmen.

(209) Or He mingleth them, males and females, and He maketh barren whom He will. Lo! He is Knower, Powerful.

(210) Nay, but I let these and their fathers enjoy life (only) till there should come unto them the Truth and a messenger making plain.
