Israfil is the angel charged with blowing the trumpet. In Sheikh Omar Abdelkafy's lessons the two blasts separate worldly life from resurrection, and he notes that some reported details have a weak chain of transmission, though other reports support them . 1

  1. وَنُفِخَ فِى ٱلصُّورِ فَصَعِقَ مَن فِى ٱلسَّمَـٰوَٰتِ وَمَن فِى ٱلْأَرْضِ إِلَّا مَن شَآءَ ٱللَّهُ ۖ ثُمَّ نُفِخَ فِيهِ أُخْرَىٰ فَإِذَا هُمْ قِيَامٌ يَنظُرُونَ

    And the trumpet is blown, and all who are in the heavens and all who are in the earth swoon away, save him whom Allah willeth. Then it is blown a second time, and behold them standing waiting!

    Qur'an 39:68

  2. يَوْمَ يُنفَخُ فِى ٱلصُّورِ فَتَأْتُونَ أَفْوَاجًا

    A day when the trumpet is blown and ye come in multitudes,

    Qur'an 78:18
