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

(201) That was because you had been exulting in the earth without any right (by worshipping others instead of Allah and by committing crimes), and that you used to rejoice extremely (in your error).

(202) Have they not travelled through the earth and seen what was the end of those before them? They were more in number than them and mightier in strength, and in the traces (they have left behind them) in the land; yet all that they used to earn availed them not.

(203) Then when their Messengers came to them with clear proofs, they were glad (and proud) with that which they had of the knowledge (of worldly things). And that at which they used to mock, surrounded them (i.e. the punishment).

(204) So when they saw Our punishment, they said: "We believe in Allah Alone and reject (all) that we used to associate with Him as (His) partners.

(205) As for 'Ad, they were arrogant in the land without right, and they said: "Who is mightier than us in strength?" See they not that Allah, Who created them was mightier in strength than them. And they used to deny Our Ayat (proofs, evidence, verses, lessons, revelations, etc.)!

(206) And as for Thamud, We showed and made clear to them the Path of Truth (Islamic Monotheism) through Our Messenger, (i.e. showed them the way of success), but they preferred blindness to guidance; so the Sa'iqah (a destructive awful cry, torment, hit, a thunderbolt) of disgracing torment seized them because of what they used to earn.

(207) And We saved those who believed and used to fear Allah, keep their duty to Him and avoid evil.

(208) Till, when they reach it (Hell-fire), their hearing (ears) and their eyes, and their skins will testify against them as to what they used to do.

(209) And they will say to their skins, "Why do you testify against us?" They will say: "Allah has caused us to speak as He causes all things to speak: and He created you the first time, and to Him you are made to return."

(210) But surely, We shall cause those who disbelieve to taste a severe torment, and certainly, We shall requite them the worst of what they used to do.
