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.”
Sunan Ibn Majah Book 6, Hadith 134
← Previous Hadith It was narrated from Abu Hurairah that the Messenger of Allah (ﷺ) offered the funeral prayer, then he came to the grave of the deceased and scattered three handfuls of earth from the side of (the deceased’s) head.

Sunan Ibn Majah Book 6, Hadith 133 Next Hadith → ‘If I were to walk on a live coal or a sword, or if I were to sew shows to my feet, that would be better for me than walking on the grave of a Muslim. And I see no difference between relieving myself in the midst of graves or in the middle of the marketplace.”

Sunan Ibn Majah Book 6, Hadith 135
