Grief and weeping
حَدَّثَنَا الْقَاسِمُ بْنُ زَكَرِيَّا بْنِ دِينَارٍ، حَدَّثَنَا إِسْحَاقُ بْنُ مَنْصُورٍ، حَدَّثَنَا أَبُو رَجَاءٍ الْخُرَاسَانِيُّ، عَنْ مُحَمَّدِ بْنِ مَالِكٍ، عَنِ الْبَرَاءِ، قَالَ كُنَّا مَعَ رَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ فِي جِنَازَةٍ فَجَلَسَ عَلَى شَفِيرِ الْقَبْرِ فَبَكَى حَتَّى بَلَّ الثَّرَى ثُمَّ قَالَ " يَا إِخْوَانِي لِمِثْلِ هَذَا فَأَعِدُّوا " .
It was narrated that Bara’ said: “We were with the Messenger of Allah (ﷺ) at a funeral, and he sat at the edge of the grave weeping, until the ground became wet. Then he said: ‘O my brothers, prepare yourselves for something like this.’”
