Ibn Abbas said: When the Prophet صلی اللہ علیہ وسلم on the day of Ashurah and commanded us to fast on it, they (i. e. Companions) said: Messenger of Allah, this is a day which is considered great by Jews and Christians ? The Messenger of Allah صلی اللہ علیہ وسلم said: When the next year comes, we shall fast on the 9th of Muharram. But the next year the Messenger of Allah صلی اللہ علیہ وسلم breathed his last.
