The Day of Ashura - the 10th Muharram - is a day of significant importance as Allah (SBT) bestowed salvation on ten of his prophets on that day. Here are these pivotal events which were due to change the course of humanity:
Our Beloved Prophet Muhammad (SAW) stated: “On the Day of Ashura Allah (SWT) created the seven heavens, seas, mountains, the Pen, Lawh-e-Mahfuz (the preserved tablet), the stars, the Throne of Allah (SBT), Angel Gibreel and all other angels. The first rain fell from the sky on the Day of Ashura.
Also, Ashura is the day in the time of our beloved prophet Muhammad (PBUH) Kaaba's covering used to be renewed on the Ashura day of every year. It was narrated from Hazrat Aisha(R.A): "Ashura is the day which Kaaba is covered." (Muslim, Abu Dawud)
