TEHRAN (Asremrooz): On the 19th of Ramadan, while praying in the Great Mosque of Kufa, Imam Ali (peace be upon him) was attacked by the Khawarij Abd-al-Rahman ibn Muljam. He was wounded by ibn Muljam's poison-coated sword while prostrating in the Fajr prayer.
Tabari and Ebn-Sa’ad wrote Imam Ali Came out the mosque then ibn Muljam hit him. on the other hand it is written by Yaquobi that there was a hole on the wall of mosque and ibn Muljam hit Imam there. But Ibn A’atham who lived in Tabari age agreed with Shia’s idea, he wrote
“The death of Imam Ali occurred before dawn on Friday 21st of Ramadhan. He was the victim of the sword of Ibin Muljuim al-Muradi , may God curse him, who attended the mosque of Kufa which he had come out of in order to wake the people up for prayers on the night of the nineteenth of that holy month.
Ibn-Muljim was lying in wait for Imam Ali (peace be upon him) from the beginning of the night. When the Imam passed by, the assassin pretended to be asleep amid a group of others. Suddenly, he sprang out and struck Imam Ali (peace be upon him) on the top of the head with a sword which was poisoned so people shouted Imam Ali (peace be upon him) was killed.
However, they took Imam Ali Home and the killer was arrested. He was asked “are you Muljiam ‘s son?” he said “yes”
He advised his sons Hazrat Imam Hassan and Hazrat (peace be upon him) Imam Hussein (peace be upon him) that from now onwards this man was their detainee and they should treat him well. They should give him the same food what they ate. He further said that if I would get well then I would decide whether to punish or forgive him. But if I could not survive and they wanted to take the revenge then they should also give him only a single cut as he gave him a single cut. He also advised them not to cut his arms and legs as it was against the teachings of Islam.
Imam Ali’s will
Imam Ali's (AS) last will to his sons Imam Hassan (AS) and Imam Hussein (AS) following a fatal blow on his head during morning prayers by Ibn Muljim (A Kharijite):
My advice to you is to be conscious of Allah and steadfast in your religion. Do not yearn for the world, and do not be seducedby it. Do not resent anything you have missed in it. Proclaim the truth; work for the next world. Oppose the oppressor andsupport the oppressed.
I advise you, and all my children, my relatives, and whosoever receives this message, to be conscious of Allah, to removeyour differences, and to strengthen your ties. I heard your grandfather, peace be upon him, say: "Reconciliation of yourdifferences is more worthy than all prayers and all fasting."
Fear Allah in matters concerning orphans. Attend to their nutrition and do not forget their interests in the middle of yours.
Fear Allah in your relations with your neighbors. Your Prophet often recommended them to you, so much so that we thought he would give them a share in inheritance.
Remain attached to the Quran. Nobody should surpass you in being intent on it, or more sincere in implementing it.
Fear Allah in relation to your prayers. It is the pillar of your religion.
Fear Allah in relation to His House; do not abandon it as long as you live. If you should do that you would abandon your dignity.
Persist in jihad in the cause of Allah, with your money, your souls, and your tongue.
Maintain communication and exchange of opinion among yourselves. Beware of disunity and enmity. Do not desist from promoting good deeds and cautioning against bad ones. Should you do that, the worst among you would be your leaders, and you will call upon Allah without response.
O Children of Abdul Muttalib! Do not shed the blood of Muslims under the banner: The Imam has been assassinated! Onlythe assassin should be condemned to death.
If I die of this stroke of his, kill him with one similar stroke. Do not mutilate him! I have heard the Prophet, peace be upon him, say: "Mutilate not even a rabid dog."
