Surat An-Nisā' - سورة النساء

يَا أَيُّهَا الَّذِينَ أُوتُوا الْكِتَابَ آمِنُوا بِمَا نَزَّلْنَا مُصَدِّقًا لِّمَا مَعَكُم مِّن قَبْلِ أَن نَّطْمِسَ وُجُوهًا فَنَرُدَّهَا عَلَىٰ أَدْبَارِهَا أَوْ نَلْعَنَهُمْ كَمَا لَعَنَّا أَصْحَابَ السَّبْتِ ۚ وَكَانَ أَمْرُ اللَّهِ مَفْعُولًا

Muhsin Khan: O you who have been given the Scripture (Jews and Christians)! Believe in what We have revealed (to Muhammad SAW) confirming what is (already) with you, before We efface faces (by making them like the back of necks; without nose, mouth, eyes, etc.) and turn them hindwards, or curse them as We cursed the Sabbath-breakers. And the Commandment of Allah is always executed.
