The word(s) "should" appears 389 time(s) in 321 verse(s) in Quran in Muhammad Habib Shakir translation.

(151) And if Allah should afflict you with harm, then there is none to remove it but He; and if He intends good to you there is none to repel His grace; He brings it to whom He pleases of His servants; and He is the Forgiving, the Merciful.

(152) And follow what is revealed to you and be patient till Allah should give judgment, and He is the best of the judges.

(153) And I do not say to you that I have the treasures of Allah and I do not know the unseen, nor do I say that I am an angel, nor do I say about those whom your eyes hold in mean estimation (that) Allah will never grant them (any) good-- Allah knows best what is in their souls-- for then most surely I should be of the unjust.

(155) He said: My Lord! I seek refuge in Thee from asking Thee that of which I have no knowledge; and if Thou shouldst not forgive me and have mercy on me, I should be of the losers.

(157) He said: O my people! have you considered if I have a clear proof from my Lord and He has given me a goodly sustenance from Himself, and I do not desire that in opposition to you I should betake myself to that which I forbid you: I desire nothing but reform so far as I am able, and with none but Allah is the direction of my affair to a right issue; on Him do I rely and to Him do I turn:

(158) But why were there not among the generations before you those possessing understanding, who should have forbidden the making of mischief in the earth, except a few of those whom We delivered from among them? And those who were unjust went after what they are made to enjoy of plenty, and they were guilty.

(159) He said: Surely it grieves me that you should take him off, and I fear lest the wolf devour him while you are heedless of him.

(160) They said: Surely if the wolf should devour him notwithstanding that we are a (strong) company, we should then certainly be losers.
