اٰل عمران — Ali 'Imran Ayat 100
يٰٓاَيُّهَا الَّذِيْنَ اٰمَنُوْٓا اِنْ تُطِيْعُوْا فَرِيْقًا مِّنَ الَّذِيْنَ اُوْتُوا الْكِتٰبَ يَرُدُّوْكُمْ بَعْدَ اِيْمَانِكُمْ كٰفِرِيْنَ
Yā ayyuhal-lażīna āmanū in tuṭī‘ū farīqam minal-lażīna ūtul-kitāba yaruddūkum ba‘da īmānikum kāfirīn(a).
"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."
