It is narrated from Sayyiduna Abu Juhayfah (may Allah be pleased with him) that he saw the Prophet (peace and blessings be upon him) in a red tent of leather. He said: I saw Sayyiduna Bilal (may Allah be pleased with him) bring out his ablution water, and I saw the people rushing towards that ablution water; whoever got some of it would rub it over his body, and whoever did not get any would take from the moisture of his companion's hand. Then I saw Sayyiduna Bilal (may Allah be pleased with him) bring out a spear and plant it in the ground, and the Messenger of Allah (peace and blessings be upon him) came out wearing a red suit of clothes, with his garment tucked up, and led the people in two rak'ahs of prayer facing the spear, and I saw people and animals passing in front of the spear.
