Virtues of Muharram 

Muharram is the best month of the year to fast after Ramadhan.
The best salah offered after Fard salah is Tahajjud salah. 

Abdullah Ibn Abbasرضى الله عنهما relates that when Rasulullahصلى الله عليه وسلم
entered Madina, he saw the Jews fasting on the day of Aashoora,
then Rasulullahصلى الله عليه وسلم asked," Why is this?"  they replied,
' It is a virtuous day. On this day Allah saved Bani Israel from the
enemy. Musaعليه السلام fasted on this day to thank Allah. Heصلى الله عليه وسلم
said : I have more rights to Musaعليه السلامthan you Jews. Rasulullahصلى الله عليه وسلم
fasted on that day and commanded others to fast on that day.

Abu Qatadahرضى الله عنه relates that Rasulullahصلى الله عليه وسلم was asked about
fasting on the Day of Aashoora. Heصلى الله عليه وسلم answered : It atones for
