MUHARRAM AND THE DAY OF AASHURA
The Month of Muharram heralds the commencement of the new Islamic year. During this month the 10th Day is called Aashura. Innumerable great events in the history of the world had occurred on this Day. Qiyaamah too will occur on a Friday which will be the 10th Muharram.
It is Sunnah to fast on the Day of Aashura. Since the Yahood also fast on this Day or they used to fast, Rasulullah (sallallahu alayhi wasallam) ordered Muslims to fast on two days, either the 9th and the 10th or the 10th and the 11th. Nabi (sallallahu alayhi wasallam) had commanded the extra day to avoid a resemblance with the Yahood. Tashabbhuh bil Kuffaar (emulating non-Muslim) is a major sin.
