Sunan Ibn Majah 2772

It was narrated from Hammad bin Zaid from Thabit, that the Prophet (ﷺ) was mentioned before Anas bin Malik and he said:“He was the best of people, the most generous of people, the most courageous of people. The people of Al-Madinah became alarmed one night, and he was the first of them to investigate the noise and din. He was riding a horse belonging to Abu Talhah, bareback, with no saddle. His sword was hanging from his neck and he was saying: ‘O people, do not be afraid,’ sending them back to their houses. Then he said of the horse, ‘We found it like a sea,’ or, ‘It is a sea.’”
