The word(s) "should" appears 190 time(s) in 163 verse(s) in Quran in Muhammad Pickthal translation.

(51) Or lest ye should say: If the Scripture had been revealed unto us, we surely had been better guided than are they. Now hath there come unto you a clear proof from your Lord, a guidance and mercy; and who doeth greater wrong than he who denieth the revelations of Allah, and turneth away from them? We award unto those who turn away from Our revelations an evil doom because of their aversion.

(52) Wait they, indeed, for nothing less than that the angels should come unto them, or thy Lord should come, or there should come one of the portents from thy Lord? In the day when one of the portents from thy Lord cometh, its belief availeth naught a soul which theretofore believed not, nor in its belief earned good (by works). Say: Wait ye! Lo! We (too) are waiting.

(53) Then Satan whispered to them that he might manifest unto them that which was hidden from them of their shame, and he said: Your Lord forbade you from this tree only lest ye should become angels or become of the immortals.

(54) Marvel ye that there should come unto you a Reminder from your Lord by means of a man among you, that he may warn you, and that ye may keep from evil, and that haply ye may find mercy.

(56) They said: Hast come unto us that we should serve Allah alone, and forsake what our fathers worshipped? Then bring upon us that wherewith thou threatenest us if thou art of the truthful!

(57) We should have invented a lie against Allah if we returned to your religion after Allah hath rescued us from it. It is not for us to return to it unless Allah our Lord should (so) will. Our Lord comprehendeth all things in knowledge. In Allah do we put our trust. Our Lord! Decide with truth between us and our folk, for Thou art the best of those who make decision.

(58) And if the people of the townships had believed and kept from evil, surely We should have opened for them blessings from the sky and from the earth. But (unto every messenger) they gave the lie, and so We seized them on account of what they used to earn.

(59) And a generation hath succeeded them who inherited the scriptures. They grasp the goods of this low life (as the price of evil-doing) and say: It will be forgiven us. And if there came to them (again) the offer of the like, they would accept it (and would sin again). Hath not the covenant of the Scripture been taken on their behalf that they should not speak aught concerning Allah save the truth? And they have studied that which is therein. And the abode of the Hereafter is better, for those who ward off (evil). Have ye then no sense?

(60) And (remember) when thy Lord brought forth from the Children of Adam, from their reins, their seed, and made them testify of themselves, (saying): Am I not your Lord? They said: Yea, verily. We testify. (That was) lest ye should say at the Day of Resurrection: Lo! of this we were unaware;
