Sahih al-Bukhari, Hadith 657 ⓘ

Narrated Abu Huraira: The Prophet said, "No prayer is heavier upon the hypocrites than the Fajr and the `Isha' prayers and if they knew what is in them (in reward), they would have attended them, even if (it was) crawling. Certainly, I felt the urge to order the Mu'adh-dhin (call-maker) so that he would pronounce Iqama, then order a man to lead the people (in prayer), then take a flame of fire so that I burn (the houses) upon those who had not left for the prayer yet."

حَدَّثَنَا عُمَرُ بْنُ حَفْصٍ، قَالَ حَدَّثَنَا أَبِي قَالَ، حَدَّثَنَا الأَعْمَشُ، قَالَ حَدَّثَنِي أَبُو صَالِحٍ، عَنْ أَبِي هُرَيْرَةَ، قَالَ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ لَيْسَ صَلاَةٌ أَثْقَلَ عَلَى الْمُنَافِقِينَ مِنَ الْفَجْرِ وَالْعِشَاءِ، وَلَوْ يَعْلَمُونَ مَا فِيهِمَا لأَتَوْهُمَا وَلَوْ حَبْوًا، لَقَدْ هَمَمْتُ أَنْ آمُرَ الْمُؤَذِّنَ فَيُقِيمَ، ثُمَّ آمُرَ رَجُلاً يَؤُمُّ النَّاسَ، ثُمَّ آخُذَ شُعَلاً مِنْ نَارٍ فَأُحَرِّقَ عَلَى مَنْ لاَ يَخْرُجُ إِلَى الصَّلاَةِ بَعْدُ ‏" ‏‏.‏
