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

(151) I seek no livelihood from them, nor do I ask that they should feed Me.

(152) And surely there hath come unto them news whereof the purport should deter,

(153) For they said; Is it a mortal man, alone among us, that we are to follow? Then indeed we should fall into error and madness.

(154) Hast thou not observed those who were forbidden conspiracy and afterward returned to that which they had been forbidden, and (now) conspire together for crime and wrongdoing and disobedience toward the messenger? And when they come unto thee they greet thee with a greeting wherewith Allah greeteth thee not, and say within themselves: Why should Allah punish us for what we say? Hell will suffice them; they will feel the heat thereof - a hapless journey's end!

(155) Allah forbiddeth you not those who warred not against you on account of religion and drove you not out from your homes, that ye should show them kindness and deal justly with them. Lo! Allah loveth the just dealers.

(156) Ye should believe in Allah and His messenger, and should strive for the cause of Allah with your wealth and your lives. That is better for you, if ye did but know.

(157) should He not know what He created? And He is the Subtile, the Aware.

(158) Or who is he that will provide for you if He should withhold His providence? Nay, but they are set in pride and frowardness.

(159) Surely I knew that I should have to meet my reckoning.

(160) If Thou shouldst leave them, they will mislead Thy slaves and will beget none save lewd ingrates.
