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

(41) cannot lead astray [turn away from Him (Allah) anyone of the believers],

(42) Say (O Muhammad صلى الله عليه وسلم): "O My slaves who believe (in the Oneness of Allah - Islamic Monotheism), be afraid of your Lord (Allah) and keep your duty to Him. Good is (the reward) for those who do good in this world, and Allah's earth is spacious (so if you cannot worship Allah at a place, then go to another)! Only those who are patient shall receive their reward in full, without reckoning. "

(43) And Allah judges with truth, while those to whom they invoke besides Him, cannot judge anything. Certainly, Allah! He is the All-Hearer, the All-Seer.

(44) Those who dispute about the Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) of Allah, without any authority that has come to them, it is greatly hateful and disgusting to Allah and to those who believe. Thus does Allah seal up the heart of every arrogant, tyrant. (So they cannot guide themselves to the Right Path).

(45) "No doubt you call me to (worship) one who cannot grant (me) my request (or respond to my invocation) in this world or in the Hereafter. And our return will be to Allah, and Al-Musrifun (i.e. polytheists and arrogants, those who commit great sins, the transgressors of Allah's set limits): they shall be the dwellers of the Fire!

(46) The good deed and the evil deed cannot be equal. Repel (the evil) with one which is better (i.e. Allah orders the faithful believers to be patient at the time of anger, and to excuse those who treat them badly) then verily he, between whom and you there was enmity, (will become) as though he was a close friend.

(47) Falsehood cannot come to it from before it or behind it: (it is) sent down by the All-Wise, Worthy of all praise (Allah عز وجل).

(48) And you cannot escape from Allah (i.e. His punishment) in the earth, and besides Allah you have neither any Wali (guardian or a protector, helper) nor any helper.

(49) Answer the Call of your Lord (i.e. accept the Islamic Monotheism, O mankind, and jinn) before there comes from Allah a Day which cannot be averted (i.e. the Day of Resurrection). You will have no refuge on that Day nor there will be for you any denying (of your crimes as they are all recorded in the Book of your deeds).

(50) (Like they then for Allah) a creature who is brought up in adornments (wearing silk and gold ornaments, i.e. women), and who in dispute cannot make herself clear?
