Musnad Ahmad 1151
It was narrated from `Abeedah, that ‘Ali (رضي الله عنه) said:
The Messenger of Allah (ﷺ) said on the day of Al-Ahzab. `They distracted us from the middle prayer until the sunset. May Allah fill their graves and houses - or stomachs - with fire.` He (the narrator) was not sure whether it was houses or stomachs. As for graves, there is no doubt about that.
حَدَّثَنَا حَجَّاجٌ، حَدَّثَنِي شُعْبَةُ، قَالَ سَمِعْتُ قَتَادَةَ، قَالَ سَمِعْتُ أَبَا حَسَّانَ، يُحَدِّثُ عَنْ عَبِيدَةَ، عَنْ عَلِيٍّ، رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَوْمَ الْأَحْزَابِ شَغَلُونَا عَنْ الصَّلَاةِ الْوُسْطَى حَتَّى آبَتْ الشَّمْسُ مَلَأَ اللَّهُ قُبُورَهُمْ وَبُيُوتَهُمْ أَوْ بُطُونَهُمْ نَارًا شَكَّ فِي الْبُيُوتِ وَالْبُطُونِ فَأَمَّا الْقُبُورُ فَلَيْسَ فِيهِ شَكٌّ‏.‏
