The word(s) "cannot" appears 64 time(s) in 63 verse(s) in Quran in Mohsin Khan translation.

(1) And (remember) when you said, "O Musa (Moses)! We cannot endure one kind of food. So invoke your Lord for us to bring forth for us of what the earth grows, its herbs, its cucumbers, its Fum (wheat or garlic), its lentils and its onions." He said, "Would you exchange that which is better for that which is lower? Go you down to any town and you shall find what you want!" And they were covered with humiliation and misery, and they drew on themselves the Wrath of Allah. That was because they used to disbelieve the Ayat (proofs, evidence, verses, lessons, signs, revelations etc.) of Allah and killed the Prophets wrongfully. That was because they disobeyed and used to transgress the bounds (in their disobedience to Allah, i.e. commit crimes and sins).

(2) And perform properly (i.e. all the ceremonies according to the ways of Prophet Muhammad صلى الله عليه وسلم), the Hajj and 'Umrah (i.e. the pilgrimage to Makkah) for Allah. But if you are prevented (from completing them), sacrifice a Hady (animal, i.e. a sheep, a cow, or a camel) such as you can afford, and do not shave your heads until the Hady reaches the place of sacrifice. And whosoever of you is ill or has an ailment in his scalp (necessitating shaving), he must pay a Fidyah (ransom) of either observing Saum (fasts) (three days) or giving Sadaqah (charity - feeding six poor persons) or offering sacrifice (one sheep). Then if you are in safety and whosoever performs the 'Umrah in the months of Hajj before (performing) the Hajj, (i.e. Hajj-at-Tamattu' and Al-Qiran), he must slaughter a Hady such as he can afford, but if he cannot afford it, he should observe Saum (fasts) three days during the Hajj and seven days after his return (to his home), making ten days in all. This is for him whose family is not present at Al-Masjid-Al-Haram (i.e. non-resident of Makkah). And fear Allah much and know that Allah is Severe in punishment.

(3) (Charity is) for Fuqara (the poor), who in Allah's Cause are restricted (from travel), and cannot move about in the land (for trade or work). The one who knows them not, thinks that they are rich because of their modesty. You may know them by their mark, they do not beg of people at all. And whatever you spend in good, surely, Allah knows it well.

(4) And if you are on a journey and cannot find a scribe, then let there be a pledge taken (mortgaging) ; then if one of you entrust the other, let the one who is entrusted discharge his trust (faithfully), and let him be afraid of Allah, his Lord. And conceal not the evidence for he, who hides it, surely his heart is sinful. And Allah is All-Knower of what you do.

(5) Allah wishes to lighten (the burden) for you; and man was created weak (cannot be patient to leave sexual intercourse with woman).

(6) Except the weak ones among men, women and children who cannot devise a plan, nor are they able to direct their way.

(7) They may hide (their crimes) from men, but they cannot hide (them) from Allah; for He is with them (by His Knowledge), when they plot by night in words that He does not approve. And Allah ever encompasses what they do.

(8) (They like to) listen to falsehood, to devour anything forbidden. So if they come to you (O Muhammad صلى الله عليه وسلم), either judge between them, or turn away from them. If you turn away from them, they cannot hurt you in the least. And if you judge, judge with justice between them. Verily, Allah loves those who act justly.

(9) Allah will not punish you for what is unintentional in your oaths, but He will punish you for your deliberate oaths; for its expiation feed ten Masakin (poor persons), on a scale of the average of that with which you feed your own families, or clothe them or manumit a slave. But whosoever cannot afford (that), then he should fast for three days. That is the expiation for the oaths when you have sworn . And protect your oaths (i.e. do not swear much) . Thus Allah make clear to you His Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that you may be grateful.

(10) If their aversion (from you, O Muhammad صلى الله عليه وسلم and from that with which you have been sent) is hard on you, (and you cannot be patient of their harm to you), then if you were able to seek a tunnel in the earth or a ladder to the sky, so that you may bring them a sign (and you cannot do it, so be patient). And had Allah willed, He could have gathered them together (all) on true guidance, so be not you one of those who are Al-Jahilun (the ignorant).
