The word(s) "cannot" appears 36 time(s) in 34 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) O ye Children of Adam! Let not Satan seduce you, in the same manner as He got your parents out of the Garden, stripping them of their raiment, to expose their shame: for he and his tribe watch you from a position where ye cannot see them: We made the evil ones friends (only) to those without faith.

(12) Go ye, then, for four months, backwards and forwards, (as ye will), throughout the land, but know ye that ye cannot frustrate Allah (by your falsehood) but that Allah will cover with shame those who reject Him.

(13) And an announcement from Allah and His Messenger, to the people (assembled) on the day of the Great Pilgrimage,- that Allah and His Messenger dissolve (treaty) obligations with the Pagans. If then, ye repent, it were best for you; but if ye turn away, know ye that ye cannot frustrate Allah. And proclaim a grievous penalty to those who reject Faith.

(14) Nay, they charge with falsehood that whose knowledge they cannot compass, even before the elucidation thereof hath reached them: thus did those before them make charges of falsehood: but see what was the end of those who did wrong!

(15) They seek to be informed by thee: "Is that true?" Say: "Aye! by my Lord! it is the very truth! and ye cannot frustrate it!"

(16) O Abraham! Seek not this. The decree of thy Lord hath gone forth: for them there cometh a penalty that cannot be turned back!

(17) And Satan will say when the matter is decided: "It was Allah Who gave you a promise of Truth: I too promised, but I failed in my promise to you. I had no authority over you except to call you but ye listened to me: then reproach not me, but reproach your own souls. I cannot listen to your cries, nor can ye listen to mine. I reject your former act in associating me with Allah. For wrong-doers there must be a grievous penalty."

(18) And worship others than Allah,- such as have no power of providing them, for sustenance, with anything in heavens or earth, and cannot possibly have such power?

(19) He cannot be questioned for His acts, but they will be questioned (for theirs).

(20) O men! Here is a parable set forth! listen to it! Those on whom, besides Allah, ye call, cannot create (even) a fly, if they all met together for the purpose! and if the fly should snatch away anything from them, they would have no power to release it from the fly. Feeble are those who petition and those whom they petition!
