The word(s) "turn" appears 484 time(s) in 428 verse(s) in Quran in Muhammad Habib Shakir translation.

(321) He has created you from a single being, then made its mate of the same (kind), and He has made for you eight of the cattle in pairs. He creates you in the wombs of your mothers-- a creation after a creation-- in triple darkness; that is Allah your Lord, His is the kingdom; there is no god but He; whence are you then turned away?

(322) If you are ungrateful, then surely Allah is Self-sufficient above all need of you; and He does not like ungratefulness in His servants; and if you are grateful, He likes it in you; and no bearer of burden shall bear the burden of another; then to your Lord is your return, then will He inform you of what you did; surely He is Cognizant of what is in the breasts.

(323) And when distress afflicts a man he calls upon his Lord turning to Him frequently; then when He makes him possess a favor from Him, he forgets that for which he called upon Him before, and sets up rivals to Allah that he may cause (men) to stray off from His path. Say: Enjoy yourself in your ungratefulness a little, surely you are of the inmates of the fire.

(324) And (as for) those who keep off from the worship of the idols and turn to Allah, they shall have good news, therefore give good news to My servants,

(325) And return to your Lord time after time and submit to Him before there comes to you the punishment, then you shall not be helped.

(326) Or it should say when it sees the punishment: Were there only a returning for me, I should be of the doers of good.

(327) Those who bear the power and those around Him celebrate the praise of their Lord and believe in Him and ask protection for those who believe: Our Lord! Thou embracest all things in mercy and knowledge, therefore grant protection to those who turn (to Thee) and follow Thy way, and save them from the punishment of the hell:

(328) He it is Who shows you His signs and sends down for you sustenance from heaven, and none minds but he who turns (to Him) again and again.

(329) The day on which you will turn back retreating; there shall be no savior for you from Allah, and whomsoever Allah causes to err, there is no guide for him:

(330) The means of access to the heavens, then reach the god of Musa, and I surely think him to be a liar. And thus the evil of his deed was made fairseeming to Firon, and he was turned away from the way; and the struggle of Firon was not (to end) in aught but destruction.
