The word(s) "forgotten" appears 6 time(s) in 5 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) None of Our revelations do We abrogate or cause to be forgotten, but We substitute something better or similar: Knowest thou not that Allah Hath power over all things?

(2) The Hypocrites, men and women, (have an understanding) with each other: They enjoin evil, and forbid what is just, and are close with their hands. They have forgotten Allah; so He hath forgotten them. Verily the Hypocrites are rebellious and perverse.

(3) And the pains of childbirth drove her to the trunk of a palm-tree: She cried (in her anguish): "Ah! would that I had died before this! would that I had been a thing forgotten and out of sight!"

(4) "Then he brought out (of the fire) before the (people) the image of a calf: It seemed to low: so they said: This is your god, and the god of Moses, but (Moses) has forgotten!"

(5) On the Day that Allah will raise them all up (again) and show them the Truth (and meaning) of their conduct. Allah has reckoned its (value), though they may have forgotten it, for Allah is Witness to all things.
