Abu Malik al-Ash’ari (Allah be pleased with him) reports that he heard the Messenger of Allah (Allah bless him & give him peace) say: “There will appear people in my Ummah, who will hold adultery, silk, alcohol and musical instruments to be lawful” (Sahih al-Bukhari)
2Abu Malik al-Ash’ari (Allah be pleased with him) narrates a similar type of Hadith, but a different wording. He reports that the Messenger of Allah (Allah bless him & give him peace) said: “Soon there will be people from my Ummah who will consume alcohol, they will change its name (by regarding it permissible. m), on there heads will be instruments of music and singing. Allah will make the ground swallow them up, and turn them into monkeys and swine” (Sahih Ibn Hibban & Sunan Ibn Majah, with a sound chain of narration).
