Anas said: A man, who had acted as secretary to the Prophet (ﷺ) apostatised from Islam and attached himself to the polytheists, so the Prophet (ﷺ) said, "The earth will not accept him." Abu Talha told me he came to the land in which the man died and found him cast on the surface of the ground. He asked the reason and was told by the people that they had buried him several times, but that the earth would not accept him. (Bukhari and Muslim.)
