Refer to the passage.

"the next day (25th may) (the chan) sent his secretaries to me, who said: ‘our lord sends us to you to say that you are here christians, saracens [muslims] and tuins. and each of you says that his doctrine is the best, and his writings—that is, books—the truest. so he wishes that you shall all meet together, and make a comparison, each one writing down his precepts, so that he himself may be able to know the truth.’ then i said: ‘blessed be god, who put this in the chan’s heart. but our scriptures tell us, the servant of god should not dispute, but should show mildness to all; so i am ready, without disputation or contention, to give reason for the faith and hope of the christians, to the best of my ability.’ they wrote down my words, and carried them back to him. then it was told the nestorians that they should look to themselves, and write down what they wished to say, and likewise to the saracens [muslims], and in the same way to the tuins.”
