In the year 10 AH (631/32 CE), a Christian envoy from Najran (now in southwestern Saudi Arabia) came to Muhammad to debate doctrines regarding ʿĪsā (Jesus). After Muhammad likened Jesus' miraculous birth to the creation of Ādam (Adam),[lower-alpha 1]—who was born to neither a mother nor a father — and when the Christians did not accept the Islamic doctrine about Jesus, Muhammad was instructed to call them to Mubahalah where each party should ask God to destroy the false party and their families.[10][11][12]
