It is narrated from Hazrat Bara’ (may Allah be pleased with him) that once we were going with the Prophet Muhammad (peace and blessings be upon him) when his gaze fell upon some people. The Prophet (peace and blessings be upon him) asked,“Why are these people gathered here?”It was informed that they were digging a grave. The Prophet (peace and blessings be upon him) quickly moved ahead of his companions until he reached near the grave and leaned over it. I too hurried forward to see what the Prophet (peace and blessings be upon him) was doing. There, the Prophet (peace and blessings be upon him) was weeping so much that the soil became wet with his tears. Then, turning towards us, he said,“Brothers! Prepare for this day.”
