Imam Muhammad (Taqi)
Son of Imam Ali (eighth Imam)
The Ninth Imam
Imam Muhammad (ibn Ali) Taqi (sometimes called Jawad and Ibn al-Rida) was the son of the eighth Imam. He was born in 196/809 in Medina and according to Shi’ite traditions was martyred in 220/835, poisoned by his wife, the daughter of Ma’mun, at the instigation of the Abbasid caliph Mu’tasim. He was buried next to his grandfather, the seventh Imam, in Kazimayn. He became Imam after the death of his father through Divine Command and by the decree of his forefathers.
At the time of the death of his father he was in Medina. Ma’mun called him to Baghdad which was then the capital of the caliphate and outwardly showed him much kindness. He even gave the Imam his daughter in marriage and kept him in Baghdad. In reality he wanted to keep a close watch upon the Imam from both outside and within his own household. The Imam spent some time in Baghdad and then with the consent of Ma’mum set out for Medina where he remained until Ma’mun’s death.
When Mu’tasim became the caliph he called the Imam back to Baghdad and, as we have seen, through the Imam’s wife had him poisoned and killed.
