Could you provide detailed information about the conquests of Rome and Persia involving Maula Ali and his sons, as well as suggestions for any relevant books on this topic?
Imam Ali (AS) and his sons never took part in any army or battle under the leadership of the wrongdoers. The narrations claiming that are fabricated and never narrated by any authentic narrator. Ibn Khaldoun claimed that in after over eight hundred years after Imam Ali's martyrdom with out mentioning any chain of narrators, that is why scholars do not take such claims as authentic at all. Such fabricated narrations aims to show that Imam Ali (AS) and his sons approved the leadership of the Saqeefa rulers, which is a false claim.
Wassalam.
