Surat At-Tawbah - سورة التوبة

يَا أَيُّهَا الَّذِينَ آمَنُوا لَا تَتَّخِذُوا آبَاءَكُمْ وَإِخْوَانَكُمْ أَوْلِيَاءَ إِنِ اسْتَحَبُّوا الْكُفْرَ عَلَى الْإِيمَانِ ۚ وَمَن يَتَوَلَّهُم مِّنكُمْ فَأُولَٰئِكَ هُمُ الظَّالِمُونَ

Muhsin Khan: O you who believe! Take not for Auliya' (supporters and helpers) your fathers and your brothers if they prefer disbelief to Belief. And whoever of you does so, then he is one of the Zalimun (wrong-doers, etc.).
