The word(s) "should" appears 240 time(s) in 207 verse(s) in Quran in Abdullah Yusuf Ali translation.

(101) And He has set up on the earth mountains standing firm, lest it should shake with you; and rivers and roads; that ye may guide yourselves;

(102) The worshippers of false gods say: "If Allah had so willed, we should not have worshipped aught but Him - neither we nor our fathers,- nor should we have prescribed prohibitions other than His." So did those who went before them. But what is the mission of messengers but to preach the Clear Message?

(103) And We sent down the Book to thee for the express purpose, that thou shouldst make clear to them those things in which they differ, and that it should be a guide and a mercy to those who believe.

(104) And be not like a woman who breaks into untwisted strands the yarn which she has spun, after it has become strong. Nor take your oaths to practise deception between yourselves, lest one party should be more numerous than another: for Allah will test you by this; and on the Day of Judgment He will certainly make clear to you (the truth of) that wherein ye disagree.

(105) The prayer that man should make for good, he maketh for evil; for man is given to hasty (deeds).

(106) These are among the (precepts of) wisdom, which thy Lord has revealed to thee. Take not, with Allah, another object of worship, lest thou shouldst be thrown into Hell, blameworthy and rejected.

(107) And We put coverings over their hearts (and minds) lest they should understand the Qur'an, and deafness into their ears: when thou dost commemorate thy Lord and Him alone in the Qur'an, they turn on their backs, fleeing (from the Truth).

(108) They say: "What! when we are reduced to bones and dust, should we really be raised up (to be) a new creation?"

(109) Say to My servants that they should (only) say those things that are best: for Satan doth sow dissensions among them: For Satan is to man an avowed enemy.

(110) In that case We should have made thee taste an equal portion (of punishment) in this life, and an equal portion in death: and moreover thou wouldst have found none to help thee against Us!
