Sunan Abi Dawud 715
سنن أبي داود#715SahihNarrated Abdullah ibn Abbas: I came riding a donkey. Another version has: Ibn Abbas said: When I was near the age of the puberty I came riding a she-ass and found the Messenger of Allah (ﷺ) leading the people in prayer at Mina. I passed in front of a part of the row (of worshippers), and dismounting left my she-ass for grazing in the pasture, and I joined the row, and no one objected to that. Abu Dawud said: These are the words of al-Qa'nabi, and are complete. Malik said: I take it as permissible at the time when the iqamah for prayer is pronounced
