صحيح مسلم

Anas b. Malik reported: There was a person amongst us who belonged to the tribe of Bani Najjar and he recited Sura al-Baqarah and Surat Al-i-'Imran and he used to transcribe for Allah's Messenger (ﷺ). He ran away as a rebel and joined the People of the Book. They gave it much importance and said: He is the person who used to transcribe for Muhammad and they were much pleased with him. Time rolled on that Allah caused his death. They dug the grave and buried him therein, but they found to their surprise that the earth had thrown him out over the surface. They again dug the grave for him and buried him but the earth again threw him out upon the surface. They again dug the grave for him and buried him but the earth again threw him out upon the surface. At last they left him unburied.
