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

(11) (And remember) when Allah said: O Jesus! Lo! I am gathering thee and causing thee to ascend unto Me, and am cleansing thee of those who disbelieve and am setting those who follow thee above those who disbelieve until the Day of Resurrection. Then unto Me ye will (all) return, and I shall judge between you as to that wherein ye used to differ.

(12) Ignominy shall be their portion wheresoever they are found save (where they grasp) a rope from Allah and a rope from men. They have incurred anger from their Lord, and wretchedness is laid upon them. That is because they used to disbelieve the revelations of Allah, and slew the prophets wrongfully. That is because they were rebellious and used to transgress.

(13) And verily ye used to wish for death before ye met it (in the field). Now ye have seen it with your eyes!

(14) Lo! those of you who turned back on the day when the two hosts met, Satan alone it was who caused them to backslide, because of some of that which they have earned. Now Allah hath forgiven them. Lo! Allah is Forgiving, Clement.

(15) And We caused the Mount to tower above them at (the taking of) their covenant: and We bade them: Enter the gate, prostrate! and We bode them: Transgress not the Sabbath! and We took from them a firm covenant.

(16) O People of the Scripture! Now hath Our messenger come unto you, expounding unto you much of that which ye used to hide in the Scripture, and forgiving much. now hath come unto you light from Allah and plain Scripture,

(17) And We caused Jesus, son of Mary, to follow in their footsteps, confirming that which was (revealed) before him in the Torah, and We bestowed on him the Gospel wherein is guidance and a light, confirming that which was (revealed) before it in the Torah - a guidance and an admonition unto those who ward off (evil).

(18) The Messiah, son of Mary, was no other than a messenger, messengers (the like of whom) had passed away before him. And his mother was a saintly woman. And they both used to eat (earthly) food. See how We make the revelations clear for them, and see how they are turned away!

(19) Those of the Children of Israel who went astray were cursed by the tongue of David, and of Jesus, son of Mary. That was because they rebelled and used to transgress.

(20) They restrained not one another from the wickedness they did. Verily evil was that they used to do!
