Then whoever argues with you about it after [this] knowledge has come to you - say, "Come, let us call our sons and your sons, our women and your women, ourselves and yourselves, then supplicate earnestly [together] and invoke the curse of Allāh upon the liars [among us]."
If anyone of the Christians disputes with you, O Messenger, regarding the matter of Jesus, and claims that he was not Allah’s servant after the correct knowledge has come to you, then say to them, ‘Come, let us call our sons and your sons, our women and your women, ourselves and yourselves; and let us gather together and then pray to Allah to send down His curse on those of us who are lying’.
