[Machine] "Umar bin Al-Khattab witnessed Uthman bin Mazhun while he was riding his camel, and Uthman was also on his camel, on the back of a hill in the Arj area. His camel pushed Uthman's camel, and Uthman's camel had passed ahead of the caravan, following the camel of the Messenger of Allah ﷺ . Uthman bin Mazhun said, 'O the cause of this trouble, my back hurts!' When the animals settled down, Umar bin Al-Khattab approached him and said, 'May Allah forgive you, Abu Al-Sa'ib. What is this name you have given me?' Uthman bin Mazhun replied, 'No, by Allah, I did not give you this name. The Messenger of Allah ﷺ named you Abu Al-Sa'ib. This is the camel in front of the caravan that leads the people. We passed by one day, and we were sitting with the Messenger of Allah ﷺ , and he said, 'This is the cause of trouble,' and he pointed with his hand, 'There will always be a strong barrier between you and turmoil, as long as he is among you.'"
