Praise be to Allaah. The word “soor” (translated here as trumpet) means a horn, like a trumpet or bugle. The Messenger of Allaah (peace and blessings of Allaah be upon him) was asked about the Trumpet and he explained it in terms of what the Arabs knew in their own language, as narrated in Sunan al-Tirmidhi (3244) and elsewhere from ‘Abd-Allaah ibn ‘Umar (may Allaah be pleased with him) who said: A Bedouin said: “O Messenger of Allaah, what is the Trumpet?’ He said: “A horn that is blown into.” Classed as saheeh by al-Albaani in al-Saheehah, 1080. With regard to the one who will blow into it, it is well known that he is Israafeel (peace be upon him). Some of the scholars narrated that there is consensus on this, and it is stated clearly in some ahaadeeth. See Fath al-Baari, 11/368.
