and when the book from allah came to them which confirms the book in their possession – and before that they used to seek victory through the medium of this very prophet over the disbelievers so when the one whom they fully recognised came to them they turned disbelievers – therefore allahs curse is upon the disbelievers.
ولما جاءهم كتاب من عند الله مصدق لما معهم وكانوا من قبل يستفتحون على الذين كفروا فلما جاءهم ما عرفوا كفروا به فلعنة الله على الكافرين
