The Prophet (sallallahu alaiyhi wassallam) has said: "The best fasts after the fasts of Ramadhan are those of the month of Muharram." Nabi (sallallahu alaiyhi wassallam) was asked with regard to the blessings of this fast, he replied:" It is a compensation for the sins of the past year." i.e. Allah will forgive the sins of the past year." (Muslim, Vol 1). Abu Qataada (radhiyallahu anhu) has related that the Prophet (sallallahu alaiyhi wassallam) has reported to have said, It is my thought that by fasting on the 10th of Muharram Allah Ta'ala will pardon the sins of the past year."
