The word(s) "increase" appears 38 time(s) in 34 verse(s) in Quran in Muhammad Pickthal translation.

(11) They only are the (true) believers whose hearts feel fear when Allah is mentioned, and when His revelations are recited unto them they increase their faith, and who trust in their Lord;

(12) And whenever a surah is revealed there are some of them who say: Which one of you hath thus increased in faith? As for those who believe, it hath increased them in faith and they rejoice (therefor).

(13) We verily have displayed (Our warnings) in this Qur'an that they may take heed, but it increaseth them in naught save aversion.

(14) And (it was a warning) when we told thee: Lo! thy Lord encompasseth mankind, and We appointed the sight which We showed thee as an ordeal for mankind, and (likewise) the Accursed Tree in the Qur'an. We warn them, but it increaseth them in naught save gross impiety.

(15) And We reveal of the Qur'an that which is a healing and a mercy for believers though it increase the evil-doers in naught save ruin.

(16) And he whom Allah guideth, he is led aright; while, as for him whom He sendeth astray, for them thou wilt find no protecting friends beside Him, and We shall assemble them on the Day of Resurrection on their faces, blind, dumb and deaf; their habitation will be hell; whenever it abateth, We increase the flame for them.

(17) They fall down on their faces, weeping, and it increaseth humility in them.

(18) We narrate unto thee their story with truth. Lo! they were young men who believed in their Lord, and We increased them in guidance.

(19) Allah increaseth in right guidance those who walk aright, and the good deeds which endure are better in thy Lord's sight for reward, and better for resort.

(20) Then exalted be Allah, the True King! And hasten not (O Muhammad) with the Qur'an ere its revelation hath been perfected unto thee, and say: My Lord! increase me in knowledge.
