«بسم الله الرحمن الرحيم من محمد عبد الله ورسوله إلى هرقل عظيم الروم سلام على من اتبع الهدى أما بعد; فإني أدعوك بدعاية الإسلام أسلم تسلم يؤتك الله أجرك مرتين فإن توليت فإن عليك إثم الأريسيين و {يَا أَهْلَ الْكِتَابِ تَعَالَوْا إِلَى كَلِمَةٍ سَوَاءٍ بَيْنَنَا وَبَيْنَكُمْ أَلَّا نَعْبُدَ إِلَّا اللَّهَ وَلا نُشْرِكَ بِهِ شَيْئاً وَلا يَتَّخِذَ بَعْضُنَا بَعْضاً أَرْبَاباً مِنْ دُونِ اللَّهِ فَإِنْ تَوَلَّوْا فَقُولُوا اشْهَدُوا بِأَنَّا مُسْلِمُونَ} »
The Prophet (peace and blessings be upon him) said:
"In the name of Allah, the Most Gracious, the Most Merciful. From Muhammad, the servant of Allah and His Messenger, to Heraclius, the great ruler of Rome. Peace be upon whoever follows guidance. To proceed: I invite you with the call of Islam. Accept Islam and you will be safe; Allah will give you your reward twice over. And if you turn away, then upon you will also be the sin of the Arisiyyin (that is, the peasants and subjects). And: 'O People of the Book! Come to a word that is equal between us and you: that we worship none but Allah, and associate nothing with Him, and that none of us takes others as lords besides Allah. Then if they turn away, say: Bear witness that we are Muslims.' [Surah Al Imran: 64]"
