Mukhtasar Sahih Bukhari — Hadith 838

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) saw a man driving a sacrificial animal, so he (peace be upon him) said: "Ride on it." He said, (O Messenger of Allah!) this is a sacrificial animal (how can I ride on it?). So he (peace be upon him) said: "Ride on it." He again said, this is a sacrificial animal. Then for the second or third time, he (peace be upon him) said: "Woe to you, ride on it."
