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!

Merits of the Helpers in Madinah (Ansaar)
Chapter: The days of Pre-Islamic Period of Ignorance
Narrated `Aisha:
'Ashura' (i.e. the tenth of Muharram) was a day on which the tribe of Quraish used to fast in the prelslamic period of ignorance. The Prophet (ﷺ) also used to fast on this day. So when he migrated to Medina, he fasted on it and ordered (the Muslims) to fast on it. When the fasting of Ramadan was enjoined, it became optional for the people to fast or not to fast on the day of Ashura.
