The word(s) "ought" appears 183 time(s) in 176 verse(s) in Quran in Muhammad Pickthal translation.

(151) (And it will be said unto them): Taste your torment (which ye inflicted). This is what ye sought to hasten.

(152) When they came in unto him and said: Peace! he answered, Peace! (and thought): Folk unknown (to me).

(153) Then he went apart unto his housefolk so that they brought a fatted calf;

(154) Then we brought forth such believers as were there.

(155) And they who believe and whose seed follow them in faith, We cause their seed to join them (there), and We deprive them of nought of their (life's) work. Every man is a pledge for that which he hath earned.

(156) Have ye thought upon Al-Lat and Al-'Uzza

(157) Those are they who will be brought nigh

(158) Will all be brought together to the tryst of an appointed day.

(159) Thus if he is of those brought nigh,

(160) His is the Sovereignty of the heavens and the earth, and unto Allah (all) things are brought back.
