The blow of the trumphet at resurrection is the duty of angel
Answer Details
In Islamic belief, the blow of the trumpet at the time of resurrection is the duty of the angel Israfil.
Israfil is one of the four archangels in Islamic tradition and is responsible for blowing the trumpet, also known as the Sur, at the time of resurrection. According to Islamic belief, when the trumpet is blown for the first time, all living beings on earth will die. When it is blown for the second time, all beings will be resurrected to stand before Allah for judgment.
The Quran describes the event of the trumpet being blown in Surah Ya-Sin, "And the Horn will be blown; and at once from the graves to their Lord they will hasten" (Quran 36:51).
Therefore, it is believed that the angel Israfil is responsible for blowing the trumpet at the time of resurrection, as it is his designated duty in Islamic theology.
