It was narrated that Abu Hurayrah (may Allaah be pleased with him) said: The Messenger of Allaah (peace and blessings of Allaah be upon him) said: “The best fasting after Ramadaan is the month of Allaah Muharram, and the best prayer after the obligatory prayer is prayer at night. (Tahajud)” (Narrated by Muslim)
Ibn Abbas (Radhiyallahu-Anhu) reports: "that the Messenger of Allah (Sallallahu-Alayhi-Wasallam) said: "The one that keeps a fast in the month of Muharram will receive the reward of thirty fasts for each fast (in this sacred month)." (At-Tabraani)
According to Ibn Abbas Radhiallaho Anhu, when the Prophet Sallallahu Alayhi Wassallam migrated to Madinah, he found that the Jews of Madinah used to fast on the 10 th day of Muharram. They said that it was the day on which the Prophet Musa Alayhis Salaam and his followers crossed the Red Sea miraculously, and the Pharaoh was drowned in its water. On hearing this from the Jews, the Prophet Sallallahu Alayhi Wassallam said, "We are more closely related to Musa than you." So the Prophet Sallallahu Alayhi Wassallam directed the Muslims to fast on the day of Ashura. (Abu Dawood)
The Prophet (Sallallahu-Alayhi-Wasallam) has exhorted and encouraged his Ummah to fast on this day. He said: "This fast[Aahura] is a compensation for the (minor) sins of the past year." (Muslim)
Ibn Abbas (Radhiyallahu-Anhu) said: "When Rasulullah (Sallallahu-Alayhi-Wasallam) observed the fast of the day of Aashora and ordered (his Companions) to fast, they said: `O Rasulullah! It is a day revered (glorified) by the Jews and Christians.' Thereupon Rasulullah said: "The coming year, if Allah wills (I remain alive), I will surely fast on the ninth (also)." (Muslim)
The Prophet (Sallallahu-Alayhi-Wasallam) said: "Observe the fast of Aashora and oppose the Jews. Fast a day before it or a day after." (Baihaqi)
Rasulullah (Sallallahu-Alayhi-Wasallam) said: "One who generously spends on his family on the day of Aashora, Allah will increase (his provision) for the whole year." (Baihaqi)
And Allah Knows Best!
