Wahb bin Kaysan (may Allah have mercy on him) says that Abdullah bin al-Zubayr (may Allah be pleased with them both), while reclining, said: Bilal (may Allah be pleased with him) sang. A man said to him: "Sang?" So he sat upright and said: "Which man of the Muhajirun have I not heard singing in a melodious tune?"
