The blowing of the trumpet (As-Sur) will be performed by the angel Israfil. This is a well-established belief in Islamic eschatology. Israfil is specifically assigned the duty of blowing the trumpet to signal the end of the world and the beginning of the Day of Judgement (Yawm al-Qiyamah).
According to Islamic teaching, there will be two blows of the trumpet. The first blow will cause all living creatures in the heavens and on earth to fall unconscious and die (except those whom Allah wills to spare), as referenced in Surah Az-Zumar (39:68). The second blow will resurrect all of creation for judgement before Allah.
Each of the other angels mentioned has a distinct role: Mikail (Michael) is responsible for managing provisions, sustenance, and natural phenomena like rainfall. Malik is the angel appointed as the guardian and keeper of Hellfire, as mentioned in Surah Az-Zukhruf (43:77). Jibril (Gabriel) is the angel of revelation, responsible for delivering Allah's messages to the prophets.
Exam tip: Associate each major angel with a single key role - Jibril with revelation, Mikail with provisions, Israfil with the trumpet, and Malik with Hellfire.
