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 ‏
