Ali 'Imran 3:100

يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِن تُطِيعُوا۟ فَرِيقًا مِّنَ ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ يَرُدُّوكُم بَعْدَ إِيمَـٰنِكُمْ كَـٰفِرِينَ

Yāayyuhā alladhīna āmanū in tuṭīʿū farīqan mina alladhīna ūtū l-kitāba yaruddūkum baʿda īmānikum kāfirīna

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.
