Amir bin Sa'd (may Allah have mercy on him) said: I attended a gathering in which Sayyiduna Abu Mas'ud and Sayyiduna Qarazah bin Ka'b (may Allah be pleased with them both) were present, and girls were singing. I said: "Subhan Allah! You do this when you are the Companions of Muhammad (peace and blessings be upon him) and the people of Badr?" They said: "We have been given permission for singing at weddings and for weeping without wailing."
