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

(21) And he said: "O my sons! Do not enter by one gate, but enter by different gates, and I cannot avail you against Allah at all. Verily! The decision rests only with Allah. In Him, I put my trust and let all those that trust, put their trust in Him."

(22) (They were reprieved) until, when the Messengers gave up hope and thought that they were denied (by their people), then came to them Our Help, and whomsoever We willed were rescued. And Our punishment cannot be warded off from the people who are Mujrimun (criminals, sinners, disbelievers, polytheists).

(23) And Shaitan (Satan) will say when the matter has been decided: "Verily, Allah promised you a promise of truth. And I too promised you, but I betrayed you. I had no authority over you except that I called you, and you responded to me. So blame me not, but blame yourselves. I cannot help you, nor can you help me. I deny your former act in associating me (Satan) as a partner with Allah (by obeying me in the life of the world). Verily, there is a painful torment for the Zalimun (polytheists and wrong-doers)."

(24) And they worship others besides Allah - such as do not and cannot own any provision for them from the heavens or the earth.

(25) When he said to his father: "O my father! Why do you worship that which hears not, sees not and cannot avail you in anything?

(26) He cannot be questioned as to what He does, while they will be questioned.

(27) He knows what is before them, and what is behind them, and they cannot intercede except for him with whom He is pleased. And they stand in awe for fear of Him.

(28) O mankind! A similitude has been coined, so listen to it (carefully): Verily those on whom you call besides Allah, cannot create (even) a fly, even though they combine together for the purpose. And if the fly snatches away a thing from them, they will have no power to release it from the fly. So weak are (both) the seeker and the sought.

(29) See how they coin similitudes for you, so they have gone astray, and they cannot find a (Right) Path.

(30) [Then Sulaiman (Solomon) said to the chief of her messengers who brought the present]: "Go back to them. We verily shall come to them with hosts that they cannot resist, and we shall drive them out from there in disgrace, and they will be abased."
