The word(s) "could" appears 107 time(s) in 102 verse(s) in Quran in Saheeh International translation.

(1) Their example is that of one who kindled a fire, but when it illuminated what was around him, Allah took away their light and left them in darkness [so] they could not see.

(2) The lightning almost snatches away their sight. Every time it lights [the way] for them, they walk therein; but when darkness comes over them, they stand [still]. And if Allah had willed, He could have taken away their hearing and their sight. Indeed, Allah is over all things competent.

(3) He said, "He says, 'It is a cow neither trained to plow the earth nor to irrigate the field, one free from fault with no spot upon her.' " They said, "Now you have come with the truth." So they slaughtered her, but they could hardly do it.

(4) And you will surely find them the most greedy of people for life - [even] more than those who associate others with Allah. One of them wishes that he could be granted life a thousand years, but it would not remove him in the least from the [coming] punishment that he should be granted life. And Allah is Seeing of what they do.

(5) Many of the People of the Scripture wish they could turn you back to disbelief after you have believed, out of envy from themselves [even] after the truth has become clear to them. So pardon and overlook until Allah delivers His command. Indeed, Allah is over all things competent.

(6) Those who followed will say, "If only we had another turn [at worldly life] so we could disassociate ourselves from them as they have disassociated themselves from us." Thus will Allah show them their deeds as regrets upon them. And they are never to emerge from the Fire.

(7) To this world and the Hereafter. And they ask you about orphans. Say, "Improvement for them is best. And if you mix your affairs with theirs - they are your brothers. And Allah knows the corrupter from the amender. And if Allah had willed, He could have put you in difficulty. Indeed, Allah is Exalted in Might and Wise.

(8) A faction of the people of the Scripture wish they could mislead you. But they do not mislead except themselves, and they perceive [it] not.

(9) Nor could he order you to take the angels and prophets as lords. Would he order you to disbelief after you had been Muslims?

(10) And how could you disbelieve while to you are being recited the verses of Allah and among you is His Messenger? And whoever holds firmly to Allah has [indeed] been guided to a straight path.
