Abdullah ibn Ja'far
Migration to Abyssinia, 615 and overseas preaching
Abdullah ibn Jafar was in Abyssinia or the oversea in-between 615 and 621 and accompanied his father (probably the rest of the family) and Sa'd ibn abi Waqqas in overseas preaching in east Asia (northeast India including Manipur and China) after leaving Abyssinia in 615 by sea. They later returned to Abyssinia by 624, and then to Arabia.
He asked for Zainab's hand, and Ali accepted it. Her marriage settlement was equal to her mother's. Ali told Ja'far not to prevent Zainab from going on a journey with Husayn, her brother.
Although Zaynab bint Ali's husband was a man of means, she lived a modest life, not a life of luxury. She and her husband were charitable to the needy people. The Arab tribes called Abdullah "the sea or the cloud of munificence".
Abdullah was also noted for his standing with Ali in battles. Ibn Hajar quoted Muhammad as having said that Abdullah was like him in character and had taken him by the right hand and prayed to God to extend His mercy over the household of Abdullah bin Ja'far. During Ali's caliphate in Kufa, Abdullah was one of his four chief lieutenants (the other three were Ali's three eldest sons). When Husayn received a request from the men of Kufa to come and lead them, Abdullah urged him not to go unless the Kufans first overthrew their Umayyad magistrates. When Husayn nevertheless left on the expedition that ended at Karbala, Abdullah sent his young sons Aun and Muhammad with his wife, Husayn's sister Zainab.
The marriage of Zainab did not diminish her strong attachment to her family. Ali also felt a great affection for his daughter and nephew and when he became the Caliph of the Muslims and moved from Medina to Kufa, Zainab and Abdullah joined him. Zainab bore four boys by the names:
- Ali ibn Abdullah
- Mohammad ibn Abdullah - Martyred at Karbala.
- Aun ibn Abdullah - Martyred at Karbala.
- Abbas ibn Abdullah
- Family tree of Abdullah ibn Ja'far
- Yahya ibn Umar- Descendant of Abdullah ibn Ja'far who led a rebellion
Correction, Muhammad, son of Abdullah ibn Ja'far and martyr of Karbala was not the biological son of Zaynab. He was the son of al-Khawsa the other wife of Abdullah bin Ja'far http://home.earthlink.net/~downloadquran/Maqtal_al-Husain.pdf Maqtal al-Husayn page 213 for more references.
