Nu’man bin Sa’d reports that a man asked Sayyiduna Ali (may Allah be pleased with him): O Commander of the Faithful! Which month’s fasting do you command me to observe after Ramadan? He replied: I have not heard anyone ask this question except one man, who asked the Messenger of Allah (peace and blessings be upon him) the same question: O Messenger of Allah! After the month of Ramadan, which month’s fasting do you command me to observe? The Prophet (peace and blessings be upon him) said: If you wish to fast after Ramadan, then fast in the month of Muharram, for it is the month of Allah. In this month, Allah accepted the repentance of a people, and He will accept the repentance of another people.
