Hadith: May Allah fill their graves and houses with fire, as they distracted us from the middle prayer until the sun set

عن عَلِي بن أبي طالب رضي الله عنه أَنَّ النَّبِيَّ - صلى الله عليه وسلم - قَالَ يَوْمَ الْخَنْدَقِ: «مَلَأ اللهُ قُبُورَهم وبُيُوتَهُم نَارًا، كَمَا شَغَلُونَا عن الصَّلاَة الوُسْطَى حَتَّى غَابَت الشَّمس». وفي لفظ لمسلم: «شَغَلُونَا عن الصَّلاَة الوُسْطَى -صلاة العصر-»، ثم صَلاَّهَا بين المغرب والعشاء». وله عن عبد الله بن مسعود قال: «حَبَسَ المُشرِكُون رسول الله صلى الله عليه وسلم عن العصر، حَتَّى احْمَرَّت الشَّمسُ أو اصْفَرَّت، فقال رسول الله صلى الله عليه وسلم : شَغَلُونَا عن الصَّلاَة الوُسْطَى -صلاة العصر-، مَلَأَ الله أَجْوَافَهُم وقُبُورَهم نَارًا (أَو حَشَا الله أَجْوَافَهُم وَقُبُورَهُم نَارًا)».
[صحيح] - [حديث علي -رضي الله عنه-: متفق عليه. حديث ابن مسعود -رضي الله عنه-: رواه مسلم]

‘Ali ibn Abi Tālib (may Allah be pleased with him) reported that the Messenger of Allah (may Allah’s peace and blessings be upon him) said: “May Allah fill their graves and houses with fire, as they distracted us from the middle prayer until the sun set.” In another narration: “They distracted us from the middle prayer”, meaning: the ‘Asr prayer. Then he offered it between the Maghrib and the ‘Ishā'. Ibn Mas‘ūd (may Allah be pleased with him) reported: The polytheists distracted the Messenger of Allah (may Allah’s peace and blessings be upon him) from observing the ‘Asr prayer till the sun became red or yellow. So the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "May Allah fill their bellies and graves with fire!"
[Authentic hadith] - [Narrated by Muslim - Narrated by Bukhari & Muslim]

Explanation

The polytheists kept the Messenger (may Allah's peace and blessings be upon him) and his Companions too preoccupied to offer the ‘Asr prayer till sunset, as they were garrisoned to protect Madīnah against them. Consequently, the Messenger (may Allah’s peace and blessings be upon) invoked Allah, the Almighty, against them, asking Him to fill their stomachs, houses, and graves with fire as a punishment for hurting him and his Companions and distracting them from offering the ‘Asr, which is the best prayer.
