حَدَّثَنَا إِسْحَاقُ، حَدَّثَنَا رَوْحٌ، حَدَّثَنَا هِشَامٌ، عَنْ مُحَمَّدٍ، عَنْ عَبِيدَةَ، عَنْ عَلِيٍّ ـ رضى الله عنه ـ عَنِ النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ يَوْمَ الْخَنْدَقِ " مَلأَ اللَّهُ عَلَيْهِمْ بُيُوتَهُمْ وَقُبُورَهُمْ نَارًا كَمَا شَغَلُونَا عَنْ صَلاَةِ الْوُسْطَى حَتَّى غَابَتِ الشَّمْسُ ".

Narrated `Ali:On the day of Al-Khandaq (i.e. Trench), the Prophet (ﷺ) said '(Let) Allah fill their (i.e. the infidels') houses and graves with fire just as they have prevented us from offering the Middle Prayer (i.e. `Asr prayer) till the sun had set
