The word(s) "used" appears 196 time(s) in 191 verse(s) in Quran in Muhammad Pickthal translation.

(91) Then We heard his prayer, and bestowed upon him John, and adjusted his wife (to bear a child) for him. Lo! they used to vie one with the other in good deeds, and they cried unto Us in longing and in fear, and were submissive unto Us.

(92) Allah will judge between you on the Day of Resurrection concerning that wherein ye used to differ.

(93) Then We sent our messengers one after another. Whenever its messenger came unto a nation they denied him; so We caused them to follow one another (to disaster) and We made them bywords. A far removal for folk who believe not!

(94) My revelations were recited unto you, but ye used to turn back on your heels,

(95) (It will be said): Were not My revelations recited unto you, and then ye used to deny them?

(96) But ye chose them for a laughing-stock until they caused you to forget remembrance of Me, while ye laughed at them.

(97) On the day when their tongues and their hands and their feet testify against them as to what they used to do,

(98) Allah hath promised such of you as believe and do good work that He will surely make them to succeed (the present rulers) in the earth even as He caused those who were before them to succeed (others); and that He will surely establish for them their religion which He hath approved for them, and will give them in exchange safety after their fear. They serve Me. They ascribe no thing as partner unto Me. Those who disbelieve henceforth, they are the miscreants.

(99) And when the children among you come to puberty then let them ask leave even as those before them used to ask it. Thus Allah maketh clear His revelations for you. Allah is Knower, Wise.

(100) Now they have denied (the Truth); but there will come unto them tidings of that whereat they used to scoff.
