Sahih al-Bukhari 2654

Musaddad narrated to us: Bishr ibn al-Mufaddal narrated to us: al-Jurayri narrated to us, from ʿAbd al-Rahman ibn Abi Bakra, from his father, may Allah be pleased with him, who said: The Prophet ﷺ said three times: “Shall I tell you about the greatest of the grave sins?” They said: “Certainly, Messenger of Allah.” He said: “Associating partners with Allah and being undutiful to one’s parents.” He sat up, having been reclining, and said: “And beware: false speech.” He kept repeating it until we said: “If only he would stop.” Ismaʿil ibn Ibrahim said: al-Jurayri narrated to us: ʿAbd al-Rahman narrated to us.
