Muhammad's son...

Muhammad's son, Abdullah, had earlier gone to the governor of Sindh, Omar Bin Hafs Al-Sufri, to seek his support for his father. When the news of the martyrdom of Muhammad reached the governor of Sindh, he sent Abdullah to a nearby king who had agreed to take the young man under his protection. However, Mansoor sent his forces that finally killed Abdullah. This was in the year 152AH. Mansoor was not yet satisfied. In the words of Amir Ali: "Mansoor now vented his rage on Medina and Basra.

Many notables in Basra who had joined Ibrahim were caught and executed. Their houses were rased to the ground; their dategroves cut down. In Medina, the properties of Bani Hasan and Bani Husain were confiscated... He even threatened with death the venerable Imam Jafifer as Sadiq for asking for the release of his properties. He threw into prison Imam Abu Hanifa and had Imam Malik cruelly flogged..." • Sons of Muhammad Bin AH Bin Abdullah Bin Abbas: Muhammad himself died before the revolution.

His eldest son, Ibrahim, was living in Palestine. Marwan Al- Hammar, the last Caliph from the Ummayades, had him killed oti the grounds that the latter was in contact with Abu Muslim, the rebel of Khorasan. Abu Abbas, who became the first Caliph from th^House of Abbas, and his brother Mansoor, had to adopt some very cruel measures to retrain their rulership. Abu Abbas shed so much blood that he became known as SAFFAH, meaning "the Shedder of Blood".

Abu Jaffer exceeded even Saffah in his cruelties. Despite the fact that Imam Sadiq (A.S) had kept himself totally away from the movement to over throw the Ummayades and therefore had no interest in the caliphate, nonetheless, Saffah had suspicions that the Imam (A.S) could be a political rival.

He therefore summoned the Imam (A.S.) to Kufa, but having no evidence at all to prove Imam's involvement in matters of statecraft, he let the Imam (A.S) go free, • Abu Jaffer: The younger brother of Saffah, and who later assumed the mane "Mansoor" (the victorious one), succeeded his brother in 136 AH. So as to keep the Caliphate safe from his rivals, he went after them all. As we have seen before, he had Muhammad Nafs-U-Zakiyya killed and his entire family destroyed.

Feanng that other members from the progeny of Imam Hasan (A,S) would raise their heads against his administration to avenge the murder of Nafs-UZakiyya, Mansoor declared a war on each member of Imam Hasan's progeny.
