Musnad Ahmad 2365
Musnad of 'Abdullah bin al-'Abbas bin 'Abdul-Muttalib from the Prophet
Ibn 'Abbas (رضي الله عنه) said: I came, when I was at the age of puberty, riding on a female donkey when the Messenger of Allah (ﷺ) was leading the people in prayer in Mina, and passed in front of part of the first row. Then I dismounted and she started to graze, and I joined the people behind the Messenger of Allah (ﷺ).
