[Machine] The Prophet ﷺ sent me to Caesar, the ruler of the Romans, with a letter. So I said, "Get permission from the Messenger of Allah ﷺ ." So they took me to Caesar and it was said to him, "There is a man at the door who claims to be the Messenger of Allah's ﷺ Messenger." They became alarmed at this, so he said, "Let him in." So I was brought in to him and he had his bishops with him. So I gave him the letter and he began to read it. In it was written, "In the name of Allah, the Most Gracious, the Most Merciful, from Muhammad, the Messenger of Allah, to Caesar, the ruler of the Romans." Then his red-faced cousin, who was a Christian monk, knelt down and said to him, "Do not read this letter today, for today it has started with something that you may dislike." The letter was read until the end, and then he told them to go out. Then he sent for me and I went in to him and he asked me and I told him. Then he sent for the bishops and gathered them together. When he read the letter, the bishop said, "By Allah, this is the same one whom Moses and Jesus (peace be upon them) gave glad tidings of. We have been waiting for him." Caesar said, "What do you command me to do?" He said, "As for me, I believe in him and I follow him." Caesar said, "I know that he is the Prophet, but if I were to follow him, my kingdom would be taken away and I would be killed by the Romans."
