The word(s) "should" appears 389 time(s) in 321 verse(s) in Quran in Muhammad Habib Shakir translation.

(131) Has not the news of those before them come to them; of the people of Nuh and Ad and Samood, and the people of Ibrahim and the dwellers of Madyan and the overthrown cities; their apostles came to them with clear arguments; so it was not Allah Who should do them injustice, but they were unjust to themselves.

(132) It shall be no crime in the weak, nor in the sick, nor in those who do not find what they should spend (to stay behind), so long as they are sincere to Allah and His Apostle; there is no way (to blame) against the doers of good; and Allah is Forgiving, Merciful;

(133) Nor in those who when they came to you that you might carry them, you said: I cannot find that on which to carry you; they went back while their eyes overflowed with tears on account of grief for not finding that which they should spend.

(134) Never stand in it; certainly a masjid founded on piety from the very first day is more deserving that you should stand in it; in it are men who love that they should be purified; and Allah loves those who purify themselves.

(135) It is not (fit) for the Prophet and those who believe that they should ask forgiveness for the polytheists, even though they should be near relatives, after it has become clear to them that they are inmates of the flaming fire.

(136) It is not (attributable to) Allah that He should lead a people astray after He has guided them; He even makes clear to them what they should guard against; surely Allah knows all things.

(137) It did not beseem the people of Medina and those round about them of the dwellers of the desert to remain behind the Apostle of Allah, nor should they desire (anything) for themselves in preference to him; this is because there afflicts them not thirst or fatigue or hunger in Allah's way, nor do they tread a path which enrages the unbelievers, nor do they attain from the enemy what they attain, but a good work is written down to them on account of it; surely Allah does not waste the reward of the doers of good;

(138) And it does not beseem the believers that they should go forth all together; why should not then a company from every party from among them go forth that they may apply themselves to obtain understanding in religion, and that they may warn their people when they come back to them that they may be cautious?

(139) And if Allah should hasten the evil to men as they desire the hastening on of good, their doom should certainly have been decreed for them; but We leave those alone who hope not for Our meeting in their inordinacy, blindly wandering on.

(140) And when Our clear communications are recited to them, those who hope not for Our meeting say: Bring a Quran other than this or change it. Say: It does not beseem me that I should change it of myself; I follow naught but what is revealed to me; surely I fear, if I disobey my Lord, the punishment of a mighty day.
