The word(s) "used" appears 281 time(s) in 264 verse(s) in Quran in Mohsin Khan translation.

(161) No person knows what is kept hidden for them of joy as a reward for what they used to do.

(162) As for those who believe (in the Oneness of Allah - Islamic Monotheism) and do righteous good deeds, for them are Gardens (Paradise) as an entertainment for what they used to do.

(163) And as for those who are Fasiqun (disbelievers and disobedient to Allah), their abode will be the Fire, every time they wish to get away therefrom, they will be put back thereto, and it will be said to them: "Taste you the torment of the Fire which you used to deny."

(164) And We made from among them (Children of Israel), leaders, giving guidance under Our Command, when they were patient and used to believe with certainty in Our Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.).

(165) Verily, your Lord will judge between them, on the Day of Resurrection, concerning that wherein they used to differ.

(166) And He caused you to inherit their lands, and their houses, and their riches, and a land which you had not trodden (before). And Allah is Able to do all things.

(167) And to Solomon (We subjected) the wind, its morning (stride from sunrise till midnoon) was a month's (journey), and its afternoon (stride from the midday decline of the sun to sunset) was a month's (journey i.e. in one day he could travel two months' (journey). And We caused a fount of (molten) brass to flow for him, and there were jinn that worked in front of him, by the Leave of his Lord. And whosoever of them turned aside from Our Command, We shall cause him to taste of the torment of the blazing Fire.

(168) Those who were deemed weak will say to those who were arrogant: "Nay, but it was your plotting by night and day: when you ordered us to disbelieve in Allah and set up rivals to Him!" And each of them (parties) will conceal their own regrets (for disobeying Allah during this worldly life), when they behold the torment. And We shall put iron collars round the necks of those who disbelieved. Are they requited aught except what they used to do?

(169) And (remember) the Day when He will gather them all together, then He will say to the angels: "Was it you that these people used to worship?"

(170) They (the angels) will say: "Glorified be You! You are our Wali (Lord) instead of them. Nay, but they used to worship the jinn; most of them were believers in them."
