- " إن كنت نذرت فاضربي، وإلا فلا ".
Sayyiduna Buraidah (may Allah be pleased with him) says that the Messenger of Allah (peace and blessings be upon him) went out for a battle. When he returned, a black girl came to him and said: "O Messenger of Allah! I had made a vow that if Allah returned you safely and in well-being, I would beat the drum (duff) before you." The Messenger of Allah (peace and blessings be upon him) said: "If you really made a vow, then beat the drum, otherwise do not." She started beating the drum. Sayyiduna Abu Bakr (may Allah be pleased with him) came, and she kept beating it. Sayyiduna Ali (may Allah be pleased with him) came, and she kept beating it. Then Sayyiduna Uthman (may Allah be pleased with him) came, and she kept beating it. Then Sayyiduna Umar (may Allah be pleased with him) came, so she put the drum under her hips and sat on it. The Messenger of Allah (peace and blessings be upon him) said: "O Umar! Shaytan is afraid of you. I was sitting and she was beating the drum, Abu Bakr came and she kept beating it, then Ali came and she kept beating it, then Uthman came and she kept beating it. Umar! When you entered, she put the drum away."
