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

(1) Nay, it has become manifest to them what they had been concealing before. But if they were returned (to the world), they would certainly revert to that which they were forbidden. And indeed they are liars.

(سورة الأنعام, Al-An'aam, Chapter #6, Verse #28)
(Arabic, Transliteration, Urdu (Ahmed Ali), Urdu (Jalandhry), Farsi, Yusuf Ali, Shakir, Picthal, Mohsin Khan, French, Spanish, Indonesian, Malay, German, Bosnian, Russian, Dutch, Italian, Portuguese, Tafsir - Jalal ad-Din, Tafsir - King Fahad Quran Complex)

(2) And among mankind is he who worships Allah as it were, upon the edge (i.e. in doubt): if good befalls him, he is content therewith; but if a trial befalls him, he turns back on his face (i.e. reverts to disbelief after embracing Islam). He loses both this world and the Hereafter. That is the evident loss.

(سورة الحج, Al-Hajj, Chapter #22, Verse #11)
(Arabic, Transliteration, Urdu (Ahmed Ali), Urdu (Jalandhry), Farsi, Yusuf Ali, Shakir, Picthal, Mohsin Khan, French, Spanish, Indonesian, Malay, German, Bosnian, Russian, Dutch, Italian, Portuguese, Tafsir - Jalal ad-Din, Tafsir - King Fahad Quran Complex)

(3) Verily, We shall remove the torment for a while. Verily you will revert (to disbelief).
