وَإِذَا قِيلَ لَهُمْ ءَامِنُوا۟ بِمَآ أَنزَلَ ٱللَّهُ قَالُوا۟ نُؤْمِنُ بِمَآ أُنزِلَ عَلَيْنَا وَيَكْفُرُونَ بِمَا وَرَآءَهُۥ وَهُوَ ٱلْحَقُّ مُصَدِّقًۭا لِّمَا مَعَهُمْ ۗ قُلْ فَلِمَ تَقْتُلُونَ أَنۢبِيَآءَ ٱللَّهِ مِن قَبْلُ إِن كُنتُم مُّؤْمِنِينَ
And when it is said unto them: Believe in that which Allah hath revealed, they say: We believe in that which was revealed unto us. And they disbelieve in that which cometh after it, though it is the truth confirming that which they possess. Say (unto them, O Muhammad): Why then slew ye the prophets of Allah aforetime, if ye are (indeed) believers?
