It is narrated from Hazrat Buraidah (may Allah be pleased with him) that when the Holy Prophet (peace and blessings be upon him) returned from a certain expedition, a black woman came to the presence of the Prophet and said, "I had vowed that if Allah brought you back safely, I would play the duff before you in celebration." The Holy Prophet (peace and blessings be upon him) said, "If you made this vow, then fulfill your vow, and if you did not, then do not do it." So she began to play the duff.
