Sunan Ibn Majah 3104

ʿAlī ibn Muḥammad narrated to us: Wakīʿ narrated to us, from Hishām—the companion of al-Dastawāʾī—from Qatādah, from Anas ibn Mālik, that a sacrificial camel was brought past the Prophet (peace and blessings be upon him), and he said, “Ride it.” The man said, “It is a sacrificial camel.” He said, “Ride it.” Anas said: I saw the man riding it alongside the Prophet (peace and blessings be upon him), with a sandal hanging around its neck.
