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

(361) Surely (as for) those who return on their backs after that guidance has become manifest to them, the Shaitan has made it a light matter to them; and He gives them respite.

(362) Surely those who disbelieve and turn away from Allah's way and oppose the Apostle after that guidance has become clear to them cannot harm Allah in any way, and He will make null their deeds.

(363) Surely those who disbelieve and turn away from Allah's way, then they die while they are unbelievers, Allah will by no means forgive them.

(364) Behold! you are those who are called upon to spend in Allah's way, but among you are those who are niggardly, and whoever is niggardly is niggardly against his own soul; and Allah is Self-sufficient and you have need (of Him), and if you turn back He will bring in your place another people, then they will not be like you.

(365) And (that) He may punish the hypocritical men and the hypocritical women, and the polytheistic men and the polytheistic women, the entertainers of evil thoughts about Allah. On them is the evil turn, and Allah is wroth with them and has cursed them and prepared hell for them, and evil is the resort.

(366) Nay! you rather thought that the Apostle and the believers would not return to their families ever, and that was made fairseeming to your hearts and you thought an evil thought and you were a people doomed to perish.

(367) Say to those of the dwellers of the desert who were left behind: You shall soon be invited (to fight) against a people possessing mighty prowess; you will fight against them until they submit; then if you obey, Allah will grant you a good reward; and if you turn back as you turned back before, He will punish you with a painful punishment.

(368) There is no harm in the blind, nor is there any harm in the lame, nor is there any harm in the sick (if they do not go forth); and whoever obeys Allah and His Apostle, He will cause him to enter gardens beneath which rivers flow, and whoever turns back, He will punish him with a painful punishment.

(369) And if those who disbelieve fight with you, they would certainly turn (their) backs, then they would not find any protector or a helper.

(370) It is they who disbelieved and turned you away from the Sacred Mosque and (turned off) the offering withheld from arriving at its destined place; and were it not for the believing men and the believing women, whom, not having known, you might have trodden down, and thus something hateful might have afflicted you on their account without knowledge-- so that Allah may cause to enter into His mercy whomsoever He pleases; had they been widely separated one from another, We would surely have punished those who disbelieved from among them with a painful punishment.
