The event of Mubahilah took place on the 9th /10th year of Hijra. A delegation of 14 Christian scholars from Najran came to discuss the truth of Islam with the Holy Prophet. Arguments were put forward by both sides. Several days went by but the Najran scholars did not listen to reason. It was then that, Allah (SWT) revealed the verse inviting them to a “Mubahila”. Mubahila is when a debate fails to reach a desired conclusion and the parties wish for the intervention of Allah’s judgement in order to examine right from wrong. The Christians of Najran accepted the challenge and at the appointed hour arrived at the place where the Mubahila was going to take place.
The Holy Prophet (s) accompanied his family members: his daughter Fatima, her husband Imam Ali and their two sons, Hassan and Hussain as his partners in the process of invoking Allah’s curse upon the lying party. As soon as the Christians’ eyes fell on the Holy Prophet’s household, they realized that those individuals were the most truthful and that chastisement would be the share of anyone who would oppose them. They therefore did not dare to participate in that invocation of the curse and, instead, agreed to pay tribute to the Holy Prophet.
