The Ansar realized that there was a concerted effort to prevent Imam Ali (a.s.) from succeeding the Prophet (S). They determined that if anyone other than Imam Ali (a.s.) was to become the Caliph, the Ansar had in Sa’d bin Ubadah a better claim than the stranger incumbent to the post.
When Umar wanted Khalid bin al-Walid to be penalized for having killed Malik bin Nuwayra, a pious Muslim, and on the same night committing adultery with his widow, for the sake of pleasing the Caliph Abu Bakr*,* Khalid replied, “ I killed Malik bin Nuwayra to please Abu Bakr just as I had killed Sa’d bin Ubadah to please you .” After this retort, Umar stopped accusing Khalid of murdering Malik bin Nuwayra.[^2] (2) Malik bin Nuwayra Umar, who was well known for his booming voice and ill temper, went around Medina brandishing his unsheathed sword and threatening dire consequences if the caliphate of Abu Bakr was not accepted.
In Medina, many companions and learned Muslims preferred to express their disagreement by staying away from open acceptance of Abu Bakr as the Caliph . They were immediately branded as friends of Ali and therefore, by implication, enemies of the caliph. Ali himself was made a target, dragged from his house and the house itself was threatened to be set on fire for refusing to acknowledge Abu Bakr as the caliph.
The well known and true companions of the Prophet (S) such as Salman, Abu Dharr al-Ghifari, Huthaifa bin al-Yeman, Malik al-Ashtar, al-Miqdad, Maytham at-Tammar, Muhammad bin Abu Bakr (the son of the caliph), Malik bin Nuwayra, Muhammad bin Abi Huthaifa, Abu Ayyub al-Ansari, Sa’sa’a bin Souhan, Qambar, Kumail ibn Ziyad, Sulaym bin Qays, and an endless list of the Prophet’s companions and Imam Ali’s companions were not only deprived of their pensions but also banished from Medina to flimsy lands.
In remoter parts of the Islamic state, people were only aware that during his last pilgrimage, the Prophet (S) had nominated Imam Ali (a.s.) as his successor and demanded that the Muslim Umma should obey him alone. At any rate, they were not aware of any parallel nomination of anyone else by the Prophet (S).
This was all the more evident from the fact that Abu Bakr, Umar, and their group claimed that the Prophet (S) had not nominated any successor and that Abu Bakr was unanimously elected at the Saqifa.
