Sunan Abi Dawud, Hadith 3199 ⓘ

Narrated Abu Burdah: On the authority of his father: The Messenger of Allah commanded us to proceed to the land of Negus. Mentioning the rest of the tradition he said that Negus said: I bear witness that he is the Messenger of Allah, and it is he about whom Christ son of Mary gave good news. It I were not in the land which I am, I would come to him and carry his shoes.

حَدَّثَنَا عَبَّادُ بْنُ مُوسَى، حَدَّثَنَا إِسْمَاعِيلُ، - يَعْنِي ابْنَ جَعْفَرٍ - عَنْ إِسْرَائِيلَ، عَنْ أَبِي إِسْحَاقَ، عَنْ أَبِي بُرْدَةَ، عَنْ أَبِيهِ، قَالَ أَمَرَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم أَنْ نَنْطَلِقَ إِلَى أَرْضِ النَّجَاشِيِّ فَذَكَرَ حَدِيثَهُ قَالَ النَّجَاشِيُّ أَشْهَدُ أَنَّهُ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَنَّهُ الَّذِي بَشَّرَ بِهِ عِيسَى ابْنُ مَرْيَمَ وَلَوْلاَ مَا أَنَا فِيهِ مِنَ الْمُلْكِ لأَتَيْتُهُ حَتَّى أَحْمِلَ نَعْلَيْهِ ‏.‏
