Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) says: On the day of Uhud a man was buried along with my father. My heart was not at ease with it, so I took him out from there and buried him separately. Imam al-Bukhari (may Allah have mercy on him) reported: Sayyiduna Jabir (may Allah be pleased with him) says: I took him out after six months, and he was just as he had been when he was laid there, except for his ear.

Sayyiduna Jabir (may Allah be pleased with him) says: My father was buried along with another man, and because of this there was some unease in my heart. So I took him out after six months, and I found nothing changed in him except a few hairs of his beard that were in contact with the ground.
