وَنُفِخَ فِى ٱلصُّورِ فَصَعِقَ مَن فِى ٱلسَّمَٰوَٰتِ وَمَن فِى ٱلْأَرْضِ إِلَّا مَن شَآءَ ٱللَّهُ ۖ ثُمَّ نُفِخَ فِيهِ أُخْرَىٰ فَإِذَا هُمْ قِيَامٌۭ 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!
