The factions are the Jews and the Christians, according to Al-Kalbi. It is said that the Christians are divided into three groups: Nestorian, Jacobite, and Melkite. And from Al-Hasan: those who formed factions against the prophets when the story of Jesus was recounted to them, they disagreed about him among the people on the day of a great witnessing, meaning from their witnessing the terror of the reckoning and recompense on the Day of Resurrection, or from the place of witnessing in it, which is the standing place. Or from the time of witnessing, or from the testimony of that day against them, and that the angels and the prophets will testify against them with their tongues, hands, and feet regarding disbelief and evil deeds. Or from the place of testimony or its time. And it is said: it is what they said and testified regarding Jesus and his mother.
