وَقَالَ ابْنُ عَبَّاسٍ: أَخْبَرَنِي أَبُو سُفْيَانَ بْنُ حَرْبٍ، أَنَّ هِرَقْلَ دَعَا تَرْجُمَانَهُ، ثُمَّ دَعَا بِكِتَابِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، فَقَرَأَهُ: بِسْمِ اللَّهِ الرَّحْمَنِ الرَّحِيمِ مِنْ مُحَمَّدٍ عَبْدِ اللَّهِ وَرَسُولِهِ إِلَى هِرَقْلَ وَيَا أَهْلَ الْكِتَابِ تَعَالَوْا إِلَى كَلِمَةٍ سَوَاءٍ بَيْنَنَا وَبَيْنَكُمُ الْآيَةَ.
صحیح بخاری · Hadith 7541
And Ibn 'Abbas narrated: Abu Sufyan bin Harb told me that Heraclius called for his translator and then asked for the letter of the Prophet (saws), and the former read it (thus): "In the Name of Allah, the Most Gracious, the Merciful. (This letter is) from Muhammad bin 'Abdullah, to Heraclius. "...O people of the Scripture (Jews and Christians): Come to a word that is just between us and you that we worship none but Allah..." (V.3:64)
