The word(s) "used" appears 81 time(s) in 79 verse(s) in Quran in Muhammad Habib Shakir translation.

(51) Gather together those who were unjust and their associates, and what they used to worship

(52) They shall say: Surely you used to come to us from the right side.

(53) Surely they used to behave proudly when it was said to them: There is no god but Allah;

(54) He shall say: By Allah! you had almost caused me to perish;

(55) And We caused to grow up for him a gourdplant.

(56) And surely they used to say:

(57) And they shall say: What is the matter with us that we do not see men whom we used to count among the vicious?

(58) He it is Who created you from dust, then from a small lifegerm, then from a clot, then He brings you forth as a child, then that you may attain your maturity, then that you may be old-- and of you there are some who are caused to die before-- and that you may reach an appointed term, and that you may understand.

(59) Then shall it be said to them: Where is that which you used to set up

(60) Besides Allah? They shall say: They are gone away from us, nay, we used not to call upon anything before. Thus does Allah confound the unbelievers.
