In the Name of Allah, the Beneficent, the Merciful
Salam Alikum Dear Believers,
The Imam Mahdi Association of Marjaeya would like to send its condolences on the martyrdom of Ameer al-Mu'mineen Imam Ali (as).
Imam Ali (as) was born in the Sacred House (i.e. the Kaba) in Mecca on Friday, the thirteenth day of the month of Rajab, thirty years after the Year of the Elephant (c.570). Nobody before or after him has ever been born in the House of God, the Most High. (It was a mark) of him being honored by God, the Most High, may His name be exalted, and of his position being dignified in its greatness.
He was the first of the family of the House and of the Companions to believe in God and His Apostle. He was the first male whom the Prophet, may God bless him and his family, summoned to Islam and who answered. He never ceased to support the religion and to strive against the polytheists. He constantly defended the faith and fought against those who supported deviation (from the truth) and despotism. He spread the teachings of the sunna (the practice of the Prophet) and the Qur'an, judged with justice and enjoined (people) to do good.
On the day of the death of the Prophet, may God bless him and his family, the community differed over his Imamate. His Shia supported him because of his outstanding merit (fadl) above all mankind, through the fact that there were gathered in him the qualities of outstanding merit, judgement and perfection, such as him being the first of the community to enter the faith, his superiority over them in knowledge of the laws, his precedence over them in fighting (jihad) and the distinction which set him apart from them in the extent of his piety, asceticism and righteousness. It was because of these qualities that the Prophet (s) had himself named Ali (a) as his successor during the event of Ghadir Khumm.
Imam Ali's (a) caliphate was defined by his relentless commitment to justice, piety, and asceticism. He was known to eat the simplest of foods and treat all people with as much kindness and compassion as a human being is capable of. He also continued his role as the greatest scholar of his time, as can be easily seen in the writings and supplications narrated from him, such as the sermons and letters of Nahjul Balagha and duas such as that of Kumail, Yastasheer, and Simaat.
The martyrdom of the Commander of the faithful, peace be on him occurred before dawn of Friday, the twenty-first of the month of Ramadan, in the year 40 A.H. He was a victim of the sword of Ibn Muljam al-Muradi, who struck him as he prayed in the Mosque of Kufa. On the day of his death he was 63 years of age.
