The Prophet (S.A.W) then invited the delegates to accept Islam as their religion but they refused and asked the Prophet (S.A.W) to pronounce his beliefs about Jesus. The Prophet (S.A.W) advised them to go and rest and that he will answer their question the next day.
Next day, Allah revealed Sura 3, (Ale Imran) verses 58, 59, 60 of the Holy Quran to the Prophet (S.A.W) which says, "Surely the likeness of Jesus is with Allah as the likeness of Adam. He created him from dust then said to him be and he became alive. This is the truth from your Lord. So be not of the disputers." Next day when the Christian delegates came to he Prophet (S.A.W) to know his views about Jesus the Prophet (S.A.W) recited these verses and said, "Jesus was only a Prophet like Adam. He was created from dust and therefore cannot be son of Allah." But they did not believe him. Allah sent another revelation which says, "That if the opponents insist in the matter even after the knowledge you have given them, tell them come let us bring our sons and your sons, our woman and your woman, ourselves and yourselves and beseech Allah and invoke His curse upon the liars" (3-60).
The Prophet (S.A.W) informed the Christians about this revelation and challenged them to have a Mubahela (maledictory conflict) with him, which the Christians agreed. Next day when they came prepared for the maledictory conflict they saw the Prophet (S.A.W) coming out with Husain (A.S.), Ali (A.S.)s second son in his arms. Hasan (A.S.) the eldest son of Ali (A.S.) holding he finger of the Prophet (S.A.W), Fatema (S.A.) Ali (A.S.)s wife and daughter of the Prophet (S.A.W) walking behind the Prophet (S.A.W) and Ali (A.S.) walking behind Fatema (S.A.). The Christians also heard the Prophet (S.A.W) instructing these four members of his family that when he supplicates they should all say `Amen. The faces that the Christian saw for the first time and the instructions that they heard the Prophet (S.A.W) giving them frightened the Christians so much that Abu Harris their leader said, "Verily I see a divine light on the faces of these combatants, truth shines in their eyes. I am sure should they pray for anything Allah will listen to their prayers and even move mountains if they asked for it. I sincerely advise you to refrain from having this maledictory conflict (Mubahela) with them and invoke the curse of Allah. Such maledictory conflicts with people like these is to invite sure death." Heeding his advice the Christians refused to have Mubahela and signed a treaty with the Prophet (S.A.W) agreeing to supply two thousand dresses of forty Dirhams each every year to the Muslims [Madarejun Naboova, Vol.2, page 498].
