Prophet Muhammad (sallallahu alaihi wa sallam) part 32 :

Abu Sufyan then added: When Heraclius had finished his speech and had read the letter, there was a great hue and cry in the Royal Court. So we turned out of the court. I told my companions that the question of Ibn-Abi-Kabsha (the Prophet Muhammad) had become so prominent that even the King of Bani Al-Asfar (Byzantine) was afraid of him. Then I started to become sure that he(the Prophet ) would be the conqueror in the near future till I embraced Islam (Allah guided me to it).

The sub narrator added that Ibn An-Natur was the Governor of Ilya (Jerusalem) and Heraclius was the head of the Christians of Sham. Ibn An-Natur narrated that once while Heraclius was visiting Ilya (Jerusalem), he got up in the morning with a sad mood. Some of his priests asked him why he as in that mood. Heraclius was a foreteller and an astrologer. He replied: "At night when I looked at the stars, I saw that the leader of those who practice circumcision had appeared (become the conqueror). Who are they who practice circumcision?" The people replied: "Except the Jews, nobody practices circumcision, so you should not be afraid of them (Jews). Just Issue orders to kill every Jew present in the country.'

While they were discussing it, a messenger sent by the king of Ghassan to convey the news of Allah's Messenger to Heraclius was brought in. Having heard the news, he (Heraclius) ordered the people to go and see whether the messenger of Ghassan was circumcised. The people, after seeing him, told Heraclius that he was circumcised. Heraclius then asked him about the Arabs. The messenger replied: "Arabs also practice circumcision."

After hearing that Heraclius remarked that sovereignty of the Arabs had appeared. Heraclius then wrote a letter to his friend in Rome who was as good as Heraclius in knowledge. Heraclius then left for Homs (a town in Syria) and stayed there till he received the reply of his letter from his friend, who agreed with him in his opinion about the emergence of the Prophet and the fact that he was a Prophet. On that, Heraclius invited all the heads of the Byzantines to assemble in his palace at Homs. When they assembled, he ordered that all the doors of his palace be closed. Then he came out and said: "O Byzantines! If success is your desire and if you seek right guidance and want your empire to remain, then give a pledge of allegiance to this Prophet (embrace Islam)."

(on hearing the views of Heraclius) the people ran towards the gates of the palace like onagers but found the doors closed. Heraclius realized their hatred towards Islam and when he lost the hope of their embracing Islam, he ordered that they should be brought back in audience.(When they returned) he said: "What was already said was just to test the strength of your conviction and I have seen it." The people prostrated before him and became pleased with him, and this was the end of Heraclius's story (in connection with his faith). (Sahih Al-Bukhari)
