The word(s) "repented" appears 3 time(s) in 3 verse(s) in Quran in Mohsin Khan translation.

(1) And when they regretted and saw that they had gone astray, they (repented and) said: "If our Lord have not mercy upon us and forgive us, we shall certainly be of the losers."

(2) But those who committed evil deeds and then repented afterwards and believed, verily, your Lord after (all) that is indeed Oft-Forgiving, Most Merciful.

(3) But as for him who repented (from polytheism and sins), believed (in the Oneness of Allah, and in His Messenger Muhammad صلى الله عليه وسلم), and did righteous deeds (in the life of this world), then he will be among those who are successful.
