Mourning of Muharram for Imam Hussain
Mourning of Muharram for Imam Hussain
From Wikipedia, the free encyclopedia The Mourning of Muharram is an important period of mourning in Shia Islam, taking place in Muharram which is the first month of the Islamic calendar. It is also called the Remembrance of Muharram (Arabic: ???? ???? or ?????? ?????). Many of the events associated with the remembrance take place in congregation halls known as Hussainia. The event marks the anniversary of the Battle of Karbala when Imam Hussain ibn Ali, the grandson of the Islamic prophet Muhammad, and a Shia Imam, was killed by the forces of the second Umayad caliph Yazid I. The event is marked by arranging 'majalis' (gatherings) to review Islamic teachings and to commemorate Imam Hussain's sacrifice. The mourning reaches its climax on the tenth day, known as Ashura, on which the forces of Yazid killed the 72 individuals who fought, including Imam Hussain and his family and supporters. The women and children left living were made prisoners and transported to Yazid's court in Damascus. The words Azadari and Majalis-e Aza have been exclusively used in connection with the remembrance ceremonies for the martyrdom of Imam Hussain. Majalis-e Aza, also known as Aza-e Husayn, includes mourning congregations, lamentations, matam and all such actions which express the emotions of grief and above all, repulsion against what Yazid stood for. The term majalis has both a grammatical meaning and a meaning which relates to Aza-e-Husayn. In its technical sense, a majalis is a meeting, a session or a gathering..

According to Shia sources, The Azadari of Muharram was started by the family of Muhammad (the Ahl-ul-Bayt) after the death of Muhammad's grandson Husayn ibn Ali at the Battle of Karbala in 680 AD. Following the battle of Karbala, Muhammad's granddaughter Zaynab binte Ali and sister of Husayn, began mourning for the fallen and making speeches against Husayn ibn Ali's opponents: Ibn Ziyad and Yazid I. News of Husayn ibn Ali's death was also spread by Imam Zain-ul-Abideen, who succeeded Husayn as the Shia Imam, via sermons and speeches throughout Iraq, Syria and Hejaz. Zainab and Zain-ul-Abideen informed the people that Yazid had martyred Imam Husayn and seventy-two of his companions including his six month old son Ali Asghar, and that their women and children were taken as prisoners to Syria. When word of mourning reached Yazid he decided to release the captive women and children from the prison in Damascus, out of fear of public revolt against his rule. He sent for Zain-ul-Abideen, informed him of the impending release and asked if he wished for anything further. Zain said he would consult with Zainab. She asked Yazid to provide a place where the people could mourn for Imam Husayn and others of Muhammad's household. A house was provided, and here Zaynab binte Ali held the first Majlis-e Aza of Husayn and started the Mourning of Muharram.[citation needed] [edit] History of commemoration Template:Shiism The mourning and commemoration for Husayn ibn Ali originated in Iraq, as this is where Husayn was martyred. However, they were held in Iran as early as the twelfth century, when both Sunnis and Shias participated in them. In the Safavid period, the annual mourning ceremonies for Imam Hosayn, combined with the ritual cursing of his enemies, acquired the status of a national institution. Expressions of grief such as sine-zani (beating the chest), zangir-zani (beating oneself with chains), and tage-zani or Qama Zani also known as Tatbeer (hitting oneself with swords or knives) emerged as common features of the proliferating mourning-processions (dasta-gardani). Mourning for the martyred Imam also takes place in assemblies held in buildings erected especially for the purpose, known either as Hussainia or takia, as well as in mosques and private houses. At these assemblies, called either rawze-khani (the recitation of Rawzat al-Shuhada by Hosayneciters and preachers would recount the deeds of the martyrs and curse their enemies, arousing the emotions of the mourners who responded by singing dirges at [edit] Azadari Movement in Lucknow The Muharram, 1795: Asaf al-Daula, Nawab of Oudh, listening at night to the maulvi reading from the scriptures during Muharram, c.1795.

A canon zoom lens set at 75 mm and f5.6 ISO 1250 (which i think helps to blur the background and with modern cameras has little effect on the quality) and 1/800 sec to freeze the motion. I am a great believer in only using flash where it is essential. I always keep my camera set to AWB for outdoor pics and adjust later if required unless the lighting is unusual. A note to anyone interested: It is better to get the shot and not to worry about too many aspects of the settings when taking a variety of different types of pictures as there are so many ways of correcting for minor imperfections later. I now use a canon 5D mk ii but this was taken on my canon 500D, an excellent backup camera.
