Abu Juhayfa reported,

I was present with the Prophet ﷺ at al-Batha. Bilal brought out the leftover water from his ablution, and the people rushed toward it, and I managed to get some of it. The Anazah was planted in the ground for him, then he led the people in prayer while donkeys, dogs, and women passed in front of him.
