Abu Maalik Ash'ari

says that he heard the Prophet

said:
"Most certainly, there will be in my Ummah people who will make lawful fornication, silk, liquor and musical instruments." (Al-Bukhari)
In another version of this narration, the Prophet

said:
"Most certainly, people from my Ummah will consume liquor which they will describe with some other name. Over their heads will be playing musical instruments and singing girls. Allah will cause the earth to swallow them, and from among them He will transform into apes and pigs." (Ibn Majah )
In another Hadith the Prophet

said:
"In this Ummah will be earthquakes, disfiguration (of faces which will be transformed into apes and pigs) and showers of stone (descending on them from the heaven)." A man from among the Muslimeen said: "O Rasulullah ! When will this be?" Rasulullah

said: "When singing girls and musical instruments will become profuse and when liquor will be consumed (in abundance)." (At-Tirmidhi)
Ali Bin Abi Taalib:radiyallahuanh narrates that the Messengers

said:
"When my Ummah indulges in fifteen misdeeds, calamities will settle on them. Among these are singing girls and musical instruments." (At-Tirmidhi)
