The word(s) "turn" appears 446 time(s) in 410 verse(s) in Quran in Mohsin Khan translation.

(111) They swear by Allah that they said nothing (bad), but really they said the word of disbelief, and they disbelieved after accepting Islam, and they resolved that (plot to murder Prophet Muhammad صلى الله عليه وسلم) which they were unable to carry out, and they could not find any cause to do so except that Allah and His Messenger had enriched them of His Bounty. If then they repent, it will be better for them, but if they turn away, Allah will punish them with a painful torment in this worldly life and in the Hereafter. And there is none for them on earth as a Wali (supporter, protector) or a helper.

(112) Then when He gave them of His Bounty, they became niggardly [refused to pay the Sadaqah (Zakat or voluntary charity)], and turned away, averse.

(113) Nor (is there blame) on those who came to you to be provided with mounts, when you said: "I can find no mounts for you," they turned back, while their eyes overflowing with tears of grief that they could not find anything to spend (for Jihad).

(114) They (the hypocrites) will present their excuses to you (Muslims), when you return to them. Say (O Muhammad صلى الله عليه وسلم) "Present no excuses, we shall not believe you. Allah has already informed us of the news concerning you. Allah and His Messenger will observe your deeds. In the end you will be brought back to the All-Knower of the unseen and the seen, then He (Allah) will inform you of what you used to do." [Tafsir At-Tabari]

(115) They will swear by Allah to you (Muslims) when you return to them, that you may turn away from them. So turn away from them. Surely, they are Rijs [i.e. Najas (impure) because of their evil deeds], and Hell is their dwelling place - a recompense for that which they used to earn.

(116) And (there are) others who have acknowledged their sins, they have mixed a deed that was righteous with another that was evil. Perhaps Allah will turn unto them in forgiveness. Surely, Allah is Oft-Forgiving, Most Merciful.

(117) (The believers whose lives Allah has purchased are) those who turn to Allah in repentance (from polytheism and hypocrisy, etc.), who worship (Him), who praise (Him), who fast (or go out in Allah's Cause), who bow down (in prayer), who prostrate themselves (in prayer), who enjoin (on people) Al-Ma'ruf (i.e. Islamic Monotheism and all what Islam has ordained) and forbid (people) from Al-Munkar (i.e. disbelief, polytheism of all kinds and all that Islam has forbidden), and who observe the limits set by Allah (do all that Allah has ordained and abstain from all kinds of sins and evil deeds which Allah has forbidden). And give glad tidings to the believers.

(118) And it is not (proper) for the believers to go out to fight (Jihad ) all together. Of every troop of them, a party only should go forth, that they (who are left behind) may get instructions in (Islamic) religion, and that they may warn their people when they return to them, so that they may beware (of evil).

(119) See they not that they are put in trial once or twice every year (with different kinds of calamities, disease, famine)? Yet, they turn not in repentance, nor do they learn a lesson (from it).

(120) And whenever there comes down a Surah (chapter from the Qur'an), they look at one another (saying): "Does any one see you?" Then they turn away. Allah has turned their hearts (from the light) because they are a people that understand not.
