Surah Ali'Imran, Verse 149

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓاْ إِن تُطِيعُواْ ٱلَّذِينَ كَفَرُواْ يَرُدُّوكُمۡ عَلَىٰٓ أَعۡقَٰبِكُمۡ فَتَنقَلِبُواْ خَٰسِرِينَ١٤٩

yāayyuhā alladhīna āmanū in tuṭīʿū alladhīna kafarū yaruddūkum ʿalā aʿqābikum fatanqalibū khāsirīna

O you who have believed, if you obey those who disbelieve, they will turn you back on your heels, and you will [then] become losers.
