The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “Among my ummah there will certainly be people who permit zinaa, silk, alcohol and musical instruments…” (Narrated by al-Bukhaari ta’leeqan, no. 5590; narrated as mawsool by al-Tabaraani and al-Bayhaqi. See al-Silsilah al-Saheehah by al-Albaani, 91).
