﴿ يَٰٓأَيُّهَا ٱلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ ءَامِنُوا۟ بِمَا نَزَّلْنَا مُصَدِّقًۭا لِّمَا مَعَكُم مِّن قَبْلِ أَن نَّطْمِسَ وُجُوهًۭا فَنَرُدَّهَا عَلَىٰٓ أَدْبَارِهَآ أَوْ نَلْعَنَهُمْ كَمَا لَعَنَّآ أَصْحَٰبَ ٱلسَّبْتِ ۚ وَكَانَ أَمْرُ ٱللَّهِ مَفْعُولًا ﴾

“O you who have been granted revelation [aforetime]! Believe in what We have [now] bestowed from on high in confirmation of whatever [of the truth] you already possess, lest We efface your hopes and bring them to an end - just as We rejected those people who broke the Sabbath: for God's will is always done.”
