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

(31) Allah does not like that the evil should be uttered in public except by him who has been wronged. And Allah is Ever All-Hearer, All-Knower.

(32) Messengers as bearers of good news as well as of warning in order that mankind should have no plea against Allah after the (coming of) Messengers. And Allah is Ever All-Powerful, All-Wise.

(33) "And why should we not believe in Allah and in that which has come to us of the truth (Islamic Monotheism)? And we wish that our Lord will admit us (in Paradise on the Day of Resurrection) along with the righteous people (Prophet Muhammad صلى الله عليه وسلم and his Companions رضي الله عنهم)."

(34) Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masakin (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn . And protect your oaths (i.e. do not swear much) . Thus Allah make clear to you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful.

(35) And obey Allah and the Messenger (Muhammad صلى الله عليه وسلم), and beware (of even coming near to drinking or gambling or Al-Ansab, or Al-Azlam, etc.) and fear Allah. Then if you turn away, you should know that it is Our Messenger's duty to convey (the Message) in the clearest way.

(36) O you who believe! Kill not the game while you are in a state of Ihram [for Hajj or 'Umrah (pilgrimage)], and whosoever of you kills it intentionally, the penalty is an offering, brought to the Ka'bah, of an eatable animal (i.e. sheep, goat, cow) equivalent to the one he killed, as adjudged by two just men among you; or, for expiation, he should feed Masakin (poor persons), or its equivalent in Saum (fasting), that he may taste the heaviness (punishment) of his deed. Allah has forgiven what is past, but whosoever commits it again, Allah will take retribution from him. And Allah is All-Mighty, All-Able of Retribution.

(37) O you who believe! When death approaches any of you, and you make a bequest, (then take) the testimony of two just men of your own folk or two others from outside, while you are travelling through the land and death befalls on you. Detain them both after As-Salat (the prayer), (then) if you are in doubt (about their truthfulness), let them both swear by Allah (saying): "We wish not for any worldly gain in this, even though he (the beneficiary) be our near relative. We shall not hide Testimony of Allah, for then indeed we should be of the sinful."

(38) If then it gets known that these two had been guilty of sin, let two others stand forth in their places, nearest in kin from among those who claim a lawful right. Let them swear by Allah (saying): "We affirm that our testimony is truer than that of both of them, and that we have not trespassed (the truth), for then indeed we should be of the wrong-doers."

(39) That should make it closer (to the fact) that their testimony would be in its true shape (and thus accepted), or else they would fear that (other) oaths would be admitted after their oaths. And fear Allah and listen (with obedience to Him). And Allah guides not the people who are Al-Fasiqun (the rebellious and disobedient).

(40) "And how should I fear those whom you associate in worship with Allah (though they can neither benefit nor harm), while you fear not that you have joined in worship with Allah things for which He has not sent down to you any authority. (So) which of the two parties has more right to be in security? If you but know."
