It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "Indeed Allah, the Mighty and Majestic, has sent me as a mercy and a guidance to all the worlds, and my Lord has commanded me to eradicate musical instruments, pipes, idols and crosses, and the affairs of the Jahiliyyah (pre-Islamic ignorance). And my Lord has sworn by His might: Whichever of My servants deliberately drinks a single sip of wine, I will make him drink the like of it of pus on the Day of Resurrection, whether I forgive him or punish him. And whoever deliberately gives it to a small Muslim child to drink, I will make him drink the like of it of pus on the Day of Resurrection, whether I forgive him or punish him. And whoever abandons it out of fear of Me, I will give him to drink from the pools of al-Quds (holiness) on the Day of Resurrection."
"And it is not lawful to sell or buy singing slave-girls, nor to trade in them; rather, they are unlawful."
