Holding commemorations and mourning ceremonies for Imam Husein (as) is a tradition established and encouraged by the imams (as).[1] There is no problem in carrying out these ceremonies in any method or format as long as haram acts aren't committed. Therefore, “receiving” Muharram and beginning mourning ceremonies before Muharram actually commences in order to remind the people of the coming of Muharram and to signify its greatness and importance isn't problematic.
