The word(s) "purpose" appears 28 time(s) in 27 verse(s) in Quran in Muhammad Pickthal translation.

(21) Hast thou seen him who maketh his desire his god, and Allah sendeth him astray purposely, and sealeth up his hearing and his heart, and setteth on his sight a covering? Then who will lead him after Allah (hath condemned him)? Will ye not then heed?

(22) And caused the earth to gush forth springs, so that the waters met for a predestined purpose.

(23) They even asked of him his guests for an ill purpose. Then We blinded their eyes (and said): Taste now My punishment after My warnings!

(24) They went betimes, strong in (this) purpose.

(25) And there are among us some who have surrendered (to Allah) and there are among us some who are unjust. And whoso hath surrendered to Allah, such have taken the right path purposefully.

(26) But as for him who cometh unto thee with earnest purpose

(27) Except as seeking (to fulfil) the purpose of his Lord Most High.
