Abu Umama reported God’s Messenger as saying: "Do not sell, buy or teach singing-girls, and the price paid for them is unlawful. To similar effect has been sent down, 'Among men are those who purchase frivolous talk' (Al-Qur'an 31:6). Ahmad, Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying that this is a gharib tradition and that ‘Ali b. Yazid the transmitter is declared to be a weak traditionist.
