Musnad Ahmad 1306
It was narrated from ‘Ali (رضي الله عنه) from the Prophet (ﷺ) that On the day of al-Ahzab, he was at one of the crossing points of the ditch and he said:
`They distracted us from the middle prayer until the sunset; may Allah fill their graves and their houses - or their bellies and their houses - with fire.”
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْحَكَمِ، عَنْ يَحْيَى بْنِ الْجَزَّارِ، عَنْ عَلِيٍّ، رَضِيَ اللَّهُ عَنْهُ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ كَانَ يَوْمَ الْأَحْزَابِ عَلَى فُرْضَةٍ مِنْ فُرَضِ الْخَنْدَقِ فَقَالَ شَغَلُونَا عَنْ صَلَاةِ الْوُسْطَى حَتَّى غَرَبَتْ الشَّمْسُ مَلَأَ اللَّهُ قُبُورَهُمْ وَبُيُوتَهُمْ أَوْ بُطُونَهُمْ وَبُيُوتَهُمْ نَارًا‏.‏
