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

(251) O you who believe! when you marry the believing women, then divorce them before you touch them, you have in their case no term which you should reckon; so make some provision for them and send them forth a goodly sending forth.

(252) You may put off whom you please of them, and you may take to you whom you please, and whom you desire of those whom you had separated provisionally; no blame attaches to you; this is most proper, so that their eyes may be cool and they may not grieve, and that they should be pleased, all of them with what you give them, and Allah knows what is in your hearts; and Allah is Knowing, Forbearing.

(253) It is not allowed to you to take women afterwards, nor that you should change them for other wives, though their beauty be pleasing to you, except what your right hand possesses and Allah is Watchful over all things.

(254) O you who believe! do not enter the houses of the Prophet unless permission is given to you for a meal, not waiting for its cooking being finished-- but when you are invited, enter, and when you have taken the food, then disperse-- not seeking to listen to talk; surely this gives the Prophet trouble, but he forbears from you, and Allah does not forbear from the truth And when you ask of them any goods, ask of them from behind a curtain; this is purer for your hearts and (for) their hearts; and it does not behove you that you should give trouble to the Apostle of Allah, nor that you should marry his wives after him ever; surely this is grievous in the sight of Allah.

(255) And a burdened soul cannot bear the burden of another and if one weighed down by burden should cry for (another to carry) its burden, not aught of it shall be carried, even though he be near of kin. You warn only those who fear their Lord in secret and keep up prayer; and whoever purifies himself, he purifies himself only for (the good of) his own soul; and to Allah is the eventual coming.

(256) And (as for) those who disbelieve, for them is the fire of hell; it shall not be finished with them entirely so that they should die, nor shall the chastisement thereof be lightened to them: even thus do We retribute every ungrateful one.

(257) And they shall cry therein for succour: O our Lord! take us out, we will do good deeds other than those which we used to do. Did We not preserve you alive long enough, so that he who would be mindful in it should mind? And there came to you the warner; therefore taste; because for the unjust, there is no helper.

(258) Surely Allah upholds the heavens and the earth lest they come to naught; and if they should come to naught, there Is none who can uphold them after Him; surely He is the Forbearing, the Forgiving.

(259) (In) behaving proudly in the land and in planning evil; and the evil plans shall not beset any save the authors of it. Then should they wait for aught except the way of the former people? For you shall not find any alteration in the course of Allah; and you shall not find any change in the course of Allah.

(260) Have they not travelled in the land and seen how was the end of those before them while they were stronger than these in power? And Allah is not such that any thing in the heavens or in the earth should escape Him; surely He is Knowing, Powerful.
