It is narrated from Ubaidullah bin Abbas (may Allah be pleased with them) that Sayyiduna Abbas (may Allah be pleased with him) had a water spout which came onto the path of Sayyiduna Umar (may Allah be pleased with him). Once, Sayyiduna Umar (may Allah be pleased with him) wore new clothes on Friday, and on the same day, two chicks were slaughtered at the house of Sayyiduna Abbas (may Allah be pleased with him). When Sayyiduna Umar (may Allah be pleased with him) reached near that water spout, water mixed with the blood of the chicks started flowing from it. That water fell on Sayyiduna Umar (may Allah be pleased with him), and it contained the blood of the chicks. Sayyiduna Umar (may Allah be pleased with him) ordered that the water spout be removed from there. He went back home, took off those clothes, wore other clothes, and came back to lead the people in prayer. After the prayer, Sayyiduna Abbas (may Allah be pleased with him) came to him and said, "By Allah! The Prophet (peace and blessings be upon him) had placed this water spout at this spot." Upon hearing this, Sayyiduna Umar (may Allah be pleased with him) said, "I ask you by oath to stand on my back and put it back where the Prophet (peace and blessings be upon him) had placed it." So Sayyiduna Abbas (may Allah be pleased with him) reinstalled the water spout in the same way.
