Sahih al-Bukhari, Hadith 2931 ⓘ
Narrated `Ali: When it was the day of the battle of Al-Ahzab (i.e. the clans), Allah's Messenger said, "O Allah! Fill their (i.e. the infidels') houses and graves with fire as they busied us so much that we did not perform the prayer (i.e. `Asr) till the sun set."
حَدَّثَنَا إِبْرَاهِيمُ بْنُ مُوسَى، أَخْبَرَنَا عِيسَى، حَدَّثَنَا هِشَامٌ، عَنْ مُحَمَّدٍ، عَنْ عَبِيدَةَ، عَنْ عَلِيٍّ ـ رضى الله عنه ـ قَالَ لَمَّا كَانَ يَوْمُ الأَحْزَابِ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " مَلأَ اللَّهُ بُيُوتَهُمْ وَقُبُورَهُمْ نَارًا، شَغَلُونَا عَنِ الصَّلاَةِ الْوُسْطَى حِينَ غَابَتِ الشَّمْسُ " .
