Muharram-ul-Haram is the world which defines the sacrifices given by the family of Prophet Mohammad (P.B.U.H).
Hazrat Imam Hassan and Hazrat Imam Hussain were the two grandsons of Prophet Mohammad (P.B.U.H) who offered their lives in the hand of Yazid to protect the religion Islam in Karbala. Beyond this other family members also sacrificed their lives for Islam.
This shows that a person who is very much strong and is threatening peoples to live their livelihoods according to his principles. It is always seen that fear (khauf) did not work any more and the day came after sacrificed of Prophet Mohammad (P.B.U.H) family members Islam goes up and the Yazid went down.
According to Islamic calendar it is the first month of year. This is one of the four holy months. Muslims also keep fast (roza) for first ten days in Muharram-ul-Haram.
