Narrated to us [Al Hasan bin Ali] and [Muhammad bin Yahya], both said: narrated to us [Abdurrazaq] from [Ma'mar] from [Az Zuhri] from [Ubaidullah bin Abdullah bin Utbah] from [Ibnu Abbas], that the Prophet, peace and blessings be upon him, wrote a letter to Heraclius that read: 'From Muhammad, peace and blessings be upon him, to Heraclius, the leader of the Romans peace be upon those who follow guidance.' [Ibnu Yahya] said from [Ibnu Abbas], that [Abu Sufyan] informed him, he said: 'We met Heraclius, and he invited us to sit before him, then he asked for the letter of the Messenger of Allah, peace and blessings be upon him, and it read: In the name of Allah, from Muhammad, the Messenger of Allah, to Heraclius, the leader of the Romans, peace be upon those who follow guidance, amma ba'du (thereafter)."'"'
