The word(s) "should" appears 190 time(s) in 163 verse(s) in Quran in Muhammad Pickthal translation.

(71) They swear by Allah that they said nothing (wrong), yet they did say the word of disbelief, and did disbelieve after their Surrender (to Allah). And they purposed that which they could not attain, and they sought revenge only that Allah by His messenger should enrich them of His bounty. If they repent it will be better for them; and if they turn away, Allah will afflict them with a painful doom in the world and the Hereafter, and they have no protecting friend nor helper in the earth.

(72) They are content that they should be with the useless and their hearts are sealed, so that they apprehend not.

(73) Nor unto those whom, when they came to thee (asking) that thou shouldst mount them, thou didst tell: I cannot find whereon to mount you. They turned back with eyes flowing with tears, for sorrow that they could not find the means to spend.

(74) Never stand (to pray) there. A place of worship which was found upon duty (to Allah) from the first day is more worthy that thou shouldst stand (to pray) therein, wherein are men who love to purify themselves. Allah loveth the purifiers.

(75) It was never Allah's (part) that He should send a folk astray after He had guided them until He had made clear unto them what they should avoid. Lo! Allah is Aware of all things.

(76) And the believers should not all go out to fight. Of every troop of them, a party only should go forth, that they (who are left behind) may gain sound knowledge in religion, and that they may warn their folk when they return to them, so that they may beware.

(77) And whenever a surah is revealed, they look one at another (as who should say): Doth anybody see you? Then they turn away. Allah turneth away their hearts because they are a folk who understand not.

(78) Say: If Allah had so willed I should not have recited it to you nor would He have made it known to you. I dwelt among you a whole lifetime before it (came to me). Have ye then no sense?

(79) Say: Is there of your partners (whom ye ascribe unto Allah) one that leadeth to the Truth? Say: Allah leadeth to the Truth. Is He Who leadeth to the Truth more deserving that He should be followed, or he who findeth not the way unless he (himself) be guided. What aileth you? How judge ye?

(80) He it is Who hath appointed for you the night that ye should rest therein and the day giving sight. Lo! herein verily are portents for a folk that heed.
