The answer is that, if one is to treat (1) something such as this as a disagreement, then similar things occurred during the lifetime of the Prophet—may Allah bless him and grant him peace. Some Companions criticized Zayd ibn Hāritha’s command, while others criticized the command of his son Usāma. More than one person also criticized some of those whom Abū Bakr and Umar appointed. Moreover, the person who made this statement was Talha, and he later retracted it. Indeed, he was among those who held [Umar] (2) in the highest esteem. Likewise, those who criticized the command of Zayd and Usāma withdrew their criticism in obedience to Allah and His Messenger.
[The Rāfidī said: The eighth disagreement concerns leadership through consultation]
His statement (3): “The eighth disagreement (4) concerns leadership (5) through consultation. After disagreeing, they agreed that Uthmān should assume the caliphate.”
The answer is that this is one of the falsehoods that all authorities on transmitted reports agree is false. No one disagreed over Uthmān’s caliphate. Rather, Abd al-Rahmān spent three days consulting the people and reported that they preferred no one to Uthmān. He consulted even the young women secluded in their chambers. Even if anyone privately harbored reservations, no one related—or said—anything, nor has anything been transmitted to us.
Things of this sort may arise in matters such as (6) these. Any matter on which people consult one another will inevitably give rise to discussion, but its occurrence cannot be asserted on the basis of mere conjecture.
