Hushaym narrated to us: and Ḥumayd narrated to us from Thābit, from Anas (and I think I heard it from Anas myself), that the Messenger of Allah (ﷺ) ﷺ passed by a man driving a sacrificial camel and said to him, “Ride it.” The man said, “It is a sacrificial camel.” He said, “Ride it,” two or three times.
