VII. The Seventh Imam, Musa, entitled al-Kazim (128/744-183/799)
The son of the sixth Imam, he was contemporary with such Abbasid caliphs as al-Mansur and Harun al-Rashid. He lived most of his life in Medina with severe restrictions placed upon him and finally died in prison in Baghdad. After him, the Imams were often not able to live in their traditional home of Medina, but were forced to remain near the caliph in Baghdad or Samarra. He is buried in Kazimayn in Iraq.
