'Imran ibn Husayn said, "The Prophet said, 'Some people of this Ummah will be swallowed up by the earth, some will be transformed into animals, and some will be bombarded with stones.' One of the Muslims asked, 'When will that be, O Messenger of Allâh?' He said, 'When singers and musical instruments will become popular, and much wine will be drunk.'" (Narrated by at-Tirmidhî)
