Sa'd ibn Ubadah
Umar hastily took Abu Bakr's hand and swore his own allegiance to the latter, an example followed by the gathered men. He later stated that he felt it was necessary to demand an immediate pledge of allegiance to Abu Bakr on top of a formal agreement, so as to avoid conflict if the Ansar later reneged and chose another leader. The meeting broke up when a violent scuffle erupted between Umar and Sa'd ibn Ubadah, perhaps indicating that the choice of Abu Bakr may not have been unanimous, with emotions running high as a result of the disagreement.
