Sunan Ibn Majah 1566
It was
narrated from Abu Hurairah said:
The Messenger of Allah (ﷺ)
said:
“If one of you were to sit on a live coal that burns him, that
would be better for him than if he were to sit on a grave.”
حَدَّثَنَا سُوَيْدُ بْنُ سَعِيدٍ، حَدَّثَنَا عَبْدُ الْعَزِيزِ بْنُ أَبِي حَازِمٍ، عَنْ سُهَيْلٍ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ: قَالَ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ ‏
"‏ لأَنْ يَجْلِسَ أَحَدُكُمْ عَلَى جَمْرَةٍ تُحْرِقُهُ خَيْرٌ لَهُ مِنْ أَنْ يَجْلِسَ عَلَى قَبْرٍ ‏"‏ ‏.‏
