The Event of Mubahala was a meeting between the Islamic prophet Muhammad and a Christian delegation from Najran (present-day Yemen), in the month of Dhu'l-Hijja, 10 AH (October 631, October 631-2, October 632-3), where Muhammad invoked a curse attempting to reveal who was lying about their religious differences. The initial effort was to invite the Najrani Christians to Islam and acknowledgement of Muhammad as a prophet. During religious discussions of similarities and differences, the topic of the divinity of ‘Īsā (Arabic: عِـيْـسَى‎, Jesus) arose.
