The event of Mubahala is about monotheism. The Holy Prophet’s (pbuh) discussion with the Christians of those days – the Christians from Najran – which had led to the day of Mubahala [and asking God to damn the liars], was about Jesus (pbuh). The Holy Prophet (pbuh) said that Jesus (pbuh) was God’s servant and prophet, but they believed in something different. They decided to organize a Mubahala. As you have heard, when they met the Christians were forced to retreat.

On the day of Mubahala [the day Prophet Muhammad (pbuh) met with Christian missionaries over the dispute concerning the Oneness of God], the Holy Prophet of Islam (pbuh) brought the dearest people with him. The important point is that the Holy Prophet (pbuh) selected his dear ones to come for Mubahala, which was supposed to help distinguish between right and wrong and to be in front of everyone's eyes. "Come! Let us gather together - our sons and your sons, our women and your women, ourselves and yourselves. Then let us earnestly pray and invoke the curse of Allah on those who lie!" [Holy Qur’an, 3:61] On no other occasion did the Prophet (pbuh) bring his children, his daughter and Imam Ali (pbuh) - his brother and successor - into the arena for promoting Islam and clarifying the truth. This shows how exceptional the day of Mubahala is.
This shows the extraordinary importance of communicating the truth and clarifying the truth. He brought them for Mubahala and told his challengers to invoke God asking that whoever is telling the truth may remain and whoever is lying be removed by divine punishment.
