Then the Prophet's Salallaho Alaihi Wasallam letter was read aloud, which rendered into English, is as follows:

"Allah's Name, the Most Affectionate, the Most Merciful. This letter is being sent by Muhammad to Heraclius, the Emperor of Rome."

"Blessed are those who follow true guidance. I invite you to embrace Islaam. If you do so, you shall be safe and secure. If you come within its fold, God will give you double reward and in case you turn your back upon it, then the burden of the sins of people shall fall on your shoulders." 

O people of the Book come to the word that is common between us and between you that we shall worship none save Allah and that we shall not associate aught with Him and that none of us shall take others as lords besides Allah. Then if they turn away, say: Bear witness that verily we are Muslims.
