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

(141) Beside Allah? They say: They have failed us; but we used not to pray to anything before. Thus doth Allah send astray the disbelievers (in His guidance).

(142) Have they not travelled in the land to see the nature of the consequence for those before them? They were more numerous than these, and mightier in power and (in the) traces (which they left behind them) in the earth. But all that they used to earn availed them not.

(143) Then, when they saw Our doom, they said: We believe in Allah only and reject (all) that we used to associate (with Him).

(144) And as for Thamud, We gave them guidance, but they preferred blindness to the guidance, so the bolt of the doom of humiliation overtook them because of what they used to earn.

(145) And We delivered those who believed and used to keep their duty to Allah.

(146) Till, when they reach it, their ears and their eyes and their skins testify against them as to what they used to do.

(147) But verily We shall cause those who disbelieve to taste an awful doom, and verily We shall requite them the worst of what they used to do.

(148) And those to whom they used to cry of old have failed them, and they perceive they have no place of refuge.

(149) And never came there unto them a prophet but they used to mock him.

(150) And Pharaoh caused a proclamation to be made among his people saying: O my people! Is not mine the sovereignty of Egypt and these rivers flowing under me? Can ye not then discern?
