حَدَّثَنَا سَعِيدُ بْنُ مَنْصُورٍ، حَدَّثَنَا خَالِدُ بْنُ عَبْدِ اللَّهِ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي أَوْفَى، قَالَ دَعَا رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى الأَحْزَابِ فَقَالَ " اللَّهُمَّ مُنْزِلَ الْكِتَابِ سَرِيعَ الْحِسَابِ اهْزِمِ الأَحْزَابَ اللَّهُمَّ اهْزِمْهُمْ وَزَلْزِلْهُمْ " .
It is narrated on the authority of Ibn Abu Aufa that the Messenger of Allah (ﷺ) cursed the tribes (who had marched upon Medina with a combined force in 5 H) and said: O Allah, Revealer of the Book, swift in (taking) account, put the tribes to rout. O Lord, defeat them and shake them.
