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

(51) And say (unto them): Act! Allah will behold your actions, and (so will) His messenger and the believers, and ye will be brought back to the Knower of the Invisible and the Visible, and He will tell you what ye used to do.

(52) Nor spend they any spending, small or great, nor do they cross a valley, but it is recorded for them, that Allah may repay them the best of what they used to do.

(53) Their home will be the Fire because of what they used to earn.

(54) Yet when He hath delivered them, behold! they rebel in the earth wrongfully. O mankind! Your rebellion is only against yourselves. (Ye have) enjoyment of the life of the world; then unto Us is your return and We shall proclaim unto you what ye used to do.

(55) There doth every soul experience that which it did aforetime, and they are returned unto Allah, their rightful Lord, and that which they used to invent hath failed them.

(56) Then will it be said unto those who dealt unjustly Taste the torment of eternity. Are ye requited aught save what ye used to earn?

(57) This world's portion (will be theirs), then unto Us is their return. Then We make them taste a dreadful doom because they used to disbelieve.

(58) And We verily did allot unto the Children of Israel a fixed abode, and did provide them with good things; and they differed not until the knowledge came unto them. Lo! thy Lord will judge between them on the Day of Resurrection concerning that wherein they used to differ.

(59) Such will not escape in the earth, nor have they any protecting friends beside Allah. For them the torment will be double. They could not bear to hear, and they used not to see.

(60) Such are they who have lost their souls, and that which they used to invent hath failed them.
