The sacred month of Muharram has special rituals and ceremonies showing to the world the importance of this great month, and what happened on the Holy Household of the Messenger (prayers and Allah's peace be upon all of them). And the sacred city of Karbala, the capital and source of Hussayni rituals, and from which many customs and traditions of Ashura have emerged, and the people preserved them for hundreds years. All these rituals reflect the humanity and the spontaneous emotions so the world see the love of Imam Al-Hussayn in the hearts of believers. Among the famous customs is carrying "Hussayni Hawdaj", and it is one of Ashura symbols that characterize the Hussayni mourning processions in Karbala.
The head of the Department of Hussayni processions and rituals of the two holy shrines of Imam Al-Hussayn and Al-Abbas (peace be upon both of them); Haj Ryad Ni'mah Al-Salman stated: "The Hussayni Hawdaj is an old tradition since the begining of the Hussayni procession, and has many meanings and connotations, it is a true embodiment of the hadith of the Holy Prophet (prayers and Allah's peace be upon him and his holy Household): "Al-Hussayn is the guidance lamp and the salvation ark." Every side of Karbal makes its own Hawdaj with special characteristics, in a way that when we look at it we know it belongs to which procession, as before there were no identification banners with the name of the procession but their hawdaj was their identification. It normally leads the mourning procession, carried out by one experienced person, as its weight can reach sometimes more than 300 Kg, and this is one of the secrets and blessings of Imam Al-Hussayn and Ahl Al-Bayt (peace be upon them) it is held easily."
Adding: "The Hawdaj has many types and sizes, new and old style, usually, oil or gas flares or electric lamps are installed on it to decorate it with colored fathers, glass pearls and a set of flowers. All placed on its iron bases manufactured perfectly. The one who sees it for the first time, might feel it is a miniature of a shining naval ship with two dragons heads, representing ancient spells."
