Sahih Bukhari

Narrated Anas:The Prophet (ﷺ) saw a man driving a Badana (i.e. camel for sacrifice) and said to him, ""Ride on it."" The man said, ""O Allah's Messenger (ﷺ)! It is a Badana."" (The Prophet (ﷺ) repeated his order) and on the third or fourth time he said, ""Ride it, (woe to you"" or said: ""May Allah be merciful to you)
