[Machine] The Messenger of Caesar used to be a neighbor to me, Yazid ibn Mu'awiyah. I said to him, "Tell me about the letter of the Messenger of Allah ﷺ to Caesar." He said, "The Messenger of Allah ﷺ sent Dihyah al-Kalbi as an emissary to Caesar, and he wrote a letter to him. He mentioned something about the story of Abbad ibn Abbad, which is the most complete and accurate narration of the incident. Then the Messenger of Allah ﷺ laughed when he invited him to Islam and he refused to accept it, and he recited this verse to him, 'Verily, you (O Muhammad) guide not whom you like, but Allah guides whom He wills.' (Quran 28:56). Then the Messenger of Allah ﷺ said to him, 'You are a messenger of a people, and you have rights, but you have come to us while we are in a state of war.' Uthman ibn 'Affan said, 'I will dress him in a yellow robe.' And a man from the Ansar said, 'I will host him.'"  

كَانَ رَسُولُ قَيْصَرَ جَارًا لِي زَمَنَيَزِيدَ بْنِ مُعَاوِيَةَ فَقُلْتُ لَهُ أَخْبِرْنِي عَنْ كِتَابِ رَسُولِ اللهِ ﷺ إِلَى قَيْصَرَ فَقَالَ إِنَّ رَسُولَ اللهِ ﷺ أَرْسَلَ دِحْيَةَ الْكَلْبِيَّ إِلَى قَيْصَرَ وَكَتَبَ مَعَهُ إِلَيْهِ كِتَابًا فَذَكَرَ نَحْوَ حَدِيثِ عَبَّادِ بْنِ عَبَّادٍ وَحَدِيثُ عَبَّادٍ أَتَمُّ وَأَحْسَنُ اقْتِصَاصًا لِلْحَدِيثِ وَزَادَ قَالَ فَضَحِكَ رَسُولُ اللهِ ﷺ حِينَ دَعَاهُ إِلَى الْإِسْلَامِ فَأَبَى أَنْ يُسْلِمَ وَتَلَا هَذِهِ الْآيَةَ {إِنَّكَ لَا تَهْدِي مَنْ أَحْبَبْتَ وَلَكِنَّ اللهَ يَهْدِي مَنْ يَشَاءُ} [القصص 56] ثُمَّ قَالَ رَسُولُ اللهِ ﷺ إِنَّكَ رَسُولُ قَوْمٍ وَإِنَّ لَكَ حَقًّا وَلَكِنْ جِئْتَنَا وَنَحْنُ مُرْمِلُونَ فَقَالَ عُثْمَانُ بْنُ عَفَّانَ أَنَا أَكْسُوهُ حُلَّةً صَفُورِيَّةً وَقَالَ رَجُلٌ مِنَ الْأَنْصَارِ عَلَيَّ ضِيَافَتُهُ
