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

(111) And if any of them should say: "Verily, I am an ilah (a god) besides Him (Allah)," such a one We should recompense with Hell. Thus We recompense the Zalimun (polytheists and wrong-doers).

(112) And We have placed on the earth firm mountains, lest it should shake with them, and We placed therein broad highways for them to pass through, that they may be guided.

(113) Say (O Muhammad صلى الله عليه وسلم): "I warn you only by the revelation (from Allah and not by the opinion of the religious scholars and others). But the deaf (who follow the religious scholars and others blindly) will not hear the call, (even) when they are warned [i.e. one should follow only the Qur'an and the Sunnah (legal ways, orders, acts of worship, and the statements of Prophet Muhammad صلى الله عليه وسلم, as the companions of the Prophet صلى الله عليه وسلم did)] .

(114) And strive hard in Allah's Cause as you ought to strive (with sincerity and with all your efforts that His Name should be superior). He has chosen you (to convey His Message of Islamic Monotheism to mankind by inviting them to His religion of Islam), and has not laid upon you in religion any hardship: it is the religion of your father Ibrahim (Abraham) (Islamic Monotheism). It is He (Allah) Who has named you Muslims both before and in this (the Qur'an), that the Messenger (Muhammad صلى الله عليه وسلم) may be a witness over you and you be witnesses over mankind! So perform As-Salat (Iqamat-as-Salat), give Zakat and hold fast to Allah [i.e. have confidence in Allah, and depend upon Him in all your affairs]. He is your Maula (Patron, Lord), what an Excellent Maula (Patron, Lord) and what an Excellent Helper!

(115) "And I seek refuge with You, My Lord! lest they should come near me."

(116) And the fifth (testimony should be) the invoking of the Curse of Allah on him if he be of those who tell a lie (against her).

(117) And the fifth (testimony) should be that the Wrath of Allah be upon her if he (her husband) speaks the truth.

(118) Verily, those who like that (the crime of) illegal sexual intercourse should be propagated among those who believe, they will have a painful torment in this world and in the Hereafter. And Allah knows and you know not.

(119) And let not those among you who are blessed with graces and wealth swear not to give (any sort of help) to their kinsmen, Al-Masakin (the poor), and those who left their homes for Allah's Cause. Let them pardon and forgive. Do you not love that Allah should forgive you? And Allah is Oft-Forgiving, Most Merciful.

(120) Is there a disease in their hearts? Or do they doubt or fear lest Allah and His Messenger (صلى الله عليه وسلم) should wrong them in judgement. Nay, it is they themselves who are the Zalimun (polytheists, hypocrites and wrong-doers).
