Jabir bin Abdullah reported,

When the day of Uhud was approaching, my father called me during the night and said, "I see that I will be among the first of the Prophet's ﷺ companions to be killed. I leave behind no one dearer to me than you, except the soul of the Messenger of Allah ﷺ. I have a debt, so pay it off, and treat your sisters kindly."Morning came, and he was the first to be killed. He was buried with another man in a single grave, but my heart was not at ease leaving him with the other, so I exhumed him after six months. He was just as I had placed him on the day of his burial, with only a slight change to his ear.

عن جابر رضي الله عنه 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 فإن علي دينا فاقض واستوص بأخواتك خيرا فأصبحنا فكان أول قتيل ودفن معه آخر في قبر ثم لم تطب نفسي أن أتركه مع الآخر فاستخرجته بعد ستة أشهر فإذا هو كيوم وضعته هنية غير أذنه
