Imam Ja'far al-Sadiq became the victim of harassment by the Abbasid family and in response to his growing popularity among the people was eventually poisoned on the orders of the caliphal-Fusul al-muhimmah, p.212; Dala’il al-imamah, p.lll: Ithbat al-wasiyah, p.142. in the tenth year of al-Mansur's reign. According to a number of sources, Abu Hanifa an-Nu'man, who founded a school of jurisprudence, was imprisoned by al-Mansur. Malik ibn Anas, the founder of another school, was flogged during his rule, but al-Mansur himself did not condone this. Al-Mansur's cousin, the governor of Madinah at the time, had ordered the flogging and was punished for doing so.Ya'qubi, vol.III, p. 86; Muruj al-dhahab, vol.III, pp. 268–270. Muhammad and Ibrahim ibn Abdallah, the grandsons of Imam Hassan ibn Ali, grandson of Muhammad, were persecuted by al-Mansur after rebelling against his reign. They escaped his persecution, but al-Mansur's anger fell upon their father Abdallah ibn Hassan and others of his family. Abdallah's sons were later defeated and killed.
