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

(241) And were it not that there should befall them a disaster for what their hands have sent before, then they should say: Our Lord! why didst Thou not send to us an apostle so that we should have followed Thy communications and been of the believers!

(242) And We have enjoined on man goodness to his parents, and if they contend with you that you should associate (others) with Me, of which you have no knowledge, do not obey them, to Me is your return, so I will inform you of what you did.

(243) So each We punished for his sin; of them was he on whom We sent down a violent storm, and of them was he whom the rumbling overtook, and of them was he whom We made to be swallowed up by the earth, and of them was he whom We drowned; and it did not beseem Allah that He should be unjust to them, but they were unjust to their own souls.

(244) O My servants who believe! surely My earth is vast, therefore Me alone should you serve.

(245) Have they not travelled in the earth and seen how was the end of those before them? They were stronger than these in prowess, and dug up the earth, and built on it in greater abundance than these have built on it, and there came to them their apostles with clear arguments; so it was not beseeming for Allah that He should deal with them unjustly, but they dealt unjustly with their own souls.

(246) And certainly We have set forth for men every kind of example in this Quran; and if you should bring them a communication, those who disbelieve would certainly say: You are naught but false claimants.

(247) And if they contend with you that you should associate with Me what you have no knowledge of, do not obey them, and keep company with them in this world kindly, and follow the way of him who turns to Me, then to Me is your return, then will I inform you of what you did--

(248) They think the allies are not gone, and if the allies should come (again) they would fain be in the deserts with the desert Arabs asking for news about you, and if they were among you they would not fight save a little.

(249) And it behoves not a believing man and a believing woman that they should have any choice in their matter when Allah and His Apostle have decided a matter; and whoever disobeys Allah and His Apostle, he surely strays off a manifest straying.

(250) And when you said to him to whom Allah had shown favor and to whom you had shown a favor: Keep your wife to yourself and be careful of (your duty to) Allah; and you concealed in your soul what Allah would bring to light, and you feared men, and Allah had a greater right that you should fear Him. But when Zaid had accomplished his want of her, We gave her to you as a wife, so that there should be no difficulty for the believers in respect of the wives of their adopted sons, when they have accomplished their want of them; and Allah's command shall be performed.
