Musnad Ahmad 33:605

Musa ibn Dawud narrated to us, Ibn Lahi'ah narrated to us, from Abu al-Zubayr, that he asked Jabir ibn Abdullah about the two testers of the grave. He said: I heard the Prophet, may Allah bless him and grant him peace, saying: "Indeed, this nation will be tested in their graves. When the believer is placed in his grave and his companions turn away from him, an angel with a harsh rebuke will come to him and say to him: 'What did you use to say about this man?' The believer will say: 'I testify that he is the Messenger of Allah and His servant.' The angel will say to him: 'Look at your seat that was for you in the Fire; Allah has saved you from it and replaced it for you with your seat that you see from Paradise.' He will see both of them. The believer will say: 'Let me go to give glad tidings to my family.' It will be said to him: 'Be still.' As for the hypocrite, he will be made to sit when his family turns away from him, and it will be said to him: 'What did you use to say about this man?' He will say: 'I do not know; I used to say what the people said.' It will be said to him: 'You did not know, and you did not follow.' Then it will be said to him: 'This is your seat that was for you in Paradise; it has been replaced for you with your seat in the Fire.'" Jabir said: I heard the Prophet, may Allah bless him and grant him peace, saying: "Every servant will be resurrected in the grave upon what he died on: the believer upon his faith, and the hypocrite upon his hypocrisy."
