وَإِذَا قِيلَ لَهُمْ آمِنُواْ بِمَا أَنزَلَ اللّهُ قَالُواْ نُؤْمِنُ بِمَا أُنزِلَ عَلَيْنَا وَيَكْفُرونَ بِمَا وَرَاءهُ وَهُوَ الْحَقُّ مُصَدِّقاً لِّمَا مَعَهُمْ قُلْ فَلِمَ تَقْتُلُونَ أَنبِيَاء اللّهِ مِن قَبْلُ إِن كُنتُم مُّؤْمِنِينَ
[2:91]
And when it is said to them, Believe in what Allah has revealed, they say: We believe in that which was revealed to us; and they deny what is besides that, while it is the truth verifying that which they have. Say: Why then did you kill Allah's Prophets before if you were indeed believers?
When it is said to them, "Believe in what Allah Hath sent down, "they say, "We believe in what was sent down to us:" yet they reject all besides, even if it be Truth confirming what is with them. Say: "Why then have ye slain the prophets of Allah in times gone by, if ye did indeed believe?"
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?
