Narrated Abdullah ibn Amr ibn al-As: The Prophet ﷺ said: The trumpet (sur) which will be blown.
Shaykh Umar Farooq Saeedi
Benefits and Issues: Angel Israfil (alayhis salam) is standing with the trumpet (soor) in his mouth, awaiting the command of Allah. When the command is given, he will blow into it and the entire world will perish. Then, by the command of Allah, he will blow into it again and all will be resurrected.
