Imam Bukhari narrates: Muhammad bin Ar'arah narrated to us, he says: Umar bin Abi Zaidah narrated to me, from Aun bin Abi Juhaifah, from his own father (may Allah be pleased with him), he narrates:

"I saw the Messenger of Allah ﷺ in a red leather tent, and I saw that Hazrat Bilal (may Allah be pleased with him) took the leftover water of the Messenger of Allah ﷺ, and I saw that the people were rushing upon that water, whoever got some water from it, he applied it upon his body, and whoever did not get anything from that water, he took the moisture of his companion's hand, then I saw Hazrat Bilal, he fixed a spear into the ground, and the Prophet ﷺ came out wearing a red suit, he had raised his lower garment above his shins, he led the people in a two-Rak'ah prayer in front of the spear, and I saw the people and the animals passing across the other side of the spear."
