يَـٰٓأَيُّهَا ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَـٰبَ ءَامِنُوا۟ بِمَا نَزَّلْنَا مُصَدِّقًا لِّمَا مَعَكُم مِّن قَبْلِ أَن نَّطْمِسَ وُجُوهًا فَنَرُدَّهَا عَلَىٰٓ أَدْبَارِهَآ أَوْ نَلْعَنَهُمْ كَمَا لَعَنَّآ أَصْحَـٰبَ ٱلسَّبْتِ ۚ وَكَانَ أَمْرُ ٱللَّهِ مَفْعُولًا 47

O you who were given the Scripture, believe in what We have sent down [to Prophet Muḥammad (ﷺ)], confirming that which is with you, before We obliterate faces and turn them toward their backs or curse them as We cursed the sabbath-breakers. And ever is the matter [i.e., decree] of Allāh accomplished.
