Discourse of Imam Muhammad Al-Baqir (as) with a group of Christians

Once Imam Muhammad al-Baqir (as) and his son were forced to report to the Umayyad caliph Heshaam in Damascus. On their return, while exiting the palace of the caliph, they saw a large gathering at the far ends of an arena, opposite the palace, in which the people were all sitting down. Imam al-Baqir inquired about them and the reason behind their gathering. People replied, these are Christian priests and monks who gather in these large numbers every year. Watch what happened next!!
