[B] The Day of Ashura (10th of Muharram) is on Saturday (24th Nov).[/B]
The Prophet (Sallallahu Alaihi Wasallam) said regarding it:
"It is a great day when Allah saved Musa (As) & his people & drowned Pharaoh & his people".(Muslim)
"Fasting on it expiates the previous year of sins." (Muslim)
It is recommended to fast either the 9th & 10th (Fri & Sat) or the 10th & 11th (Sat & Sun) of Muharram to differ from the Jews & because the Prophet (Sallallahu Alaihi Wasallam) intended to fast the 9th & 10th.
So let us fast on both of these days and gain immense rewards as well as a years sins forgiven for surely we are in dire need of as many good deeds as possible before our imminent departure from this world which could be at any second.
