Do you know why the month of Muharram is the month of Allah? Muharram is a sacred month. Prophet Muhammad (PBUH) said: “The best month to fast after Ramadan is Muharram.” Prophet Muhammad (PBUH) called the month of Muharram the month of Allah. No other month has been called shahrullahi other than Muharram.
It is month that Prophet Muhammad (PBUH) would fast regularly and he would fast the day of Ashura always. Fasting on this day earns us great reward.
