Surah Aal-i-Imraan, Verse 100
يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن تُطِيعُوا۟ فَرِيقًۭا مِّنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ يَرُدُّوكُم بَعْدَ إِيمَٰنِكُمْ كَٰفِرِينَ
Translation — Sahih International
O you who have believed, if you obey a party of those who were given the Scripture, they would turn you back, after your belief, [to being] unbelievers.
