Jabir bin Abdullah reported,

Jabir reported, "When the Battle of Uhud was approaching, my father called me during the night and said, 'I see myself as one who will be killed, perhaps among the first of the Prophet's ﷺ companions to fall. I am not leaving behind anyone more beloved to me than you, after the person of the Messenger of Allah ﷺ himself. I have a debt outstanding, so settle it on my behalf, and treat your sisters well.'The morning came, and he was indeed the first to be killed. He was buried together with another man in a single grave. Then it weighed on me to leave him with someone else, so I exhumed him after six months, and there he was, exactly as I had laid him, except for a slight change to his ear."

Sahih

عن جابر قال

لما حضر أحد دعاني أبي من الليل فقال: ما أراني إلا مقتولا في أول من يقتل من أصحاب النبي ﷺ، وإني لا أترك بعدي أعز علي منك غير نفس رسول الله ﷺ، وإن على دينا فاقض، واستوص بأخواتك خيرا، فأصبحنا فكان أول قتيل، ودفن معه آخر في قبر، ثم تطب نفسي أن أتركه مع الآخر، فاستخرجته بعد ستة أشهر، فإذا هو كيوم وضعته هنية غير أذنه.
