The word(s) "should" appears 194 time(s) in 173 verse(s) in Quran in Mohsin Khan translation.

(151) "And truly, I seek refuge with my Lord and your Lord, lest you should stone me (or call me a sorcerer or kill me).

(152) Do they then await (anything) other than the Hour, that it should come upon them suddenly? But some of its portents (indications and signs) have already come; and when it (actually) is on them, how can they benefit then by their reminder?

(153) Had We willed, We could have shown them to you, and you should have known them by their marks; but surely, you will know them by the tone of their speech! And Allah knows (all) your deeds.

(154) O you who believe! Raise not your voices above the voice of the Prophet (صلى الله عليه وسلم), nor speak aloud to him in talk as you speak aloud to one another, lest your deeds should be rendered fruitless while you perceive not.

(155) O you who believe! If a Fasiq (liar - evil person) comes to you with any news, verify it, lest you should harm people in ignorance, and afterwards you become regretful for what you have done.

(156) And I (Allah) created not the jinn and mankind except that they should worship Me (Alone).

(157) I seek not any provision from them (i.e. provision for themselves or for My creatures) nor do I ask that they should feed Me (i.e. feed themselves or My creatures).

(158) And they said: "A man, alone among us - shall we follow him? Truly then we should be in error and distress (or madness)!"

(159) And he who finds not (the money for freeing a slave) must fast two successive months before they both touch each other. And he who is unable to do so, should feed sixty Miskins (poor). That is in order that you may have perfect Faith in Allah and His Messenger. These are the limits set by Allah. And for disbelievers, there is a painful torment.

(160) Have you not seen those who were forbidden to hold secret counsels, and afterwards returned to that which they had been forbidden, and conspired together for sin and wrong doing and disobedience to the Messenger (Muhammad صلى الله عليه وسلم). And when they come to you, they greet you with a greeting wherewith Allah greets you not, and say within themselves: "Why should Allah punish us not for what we say?" Hell will be sufficient for them; they will burn therein. And worst indeed is that destination!
