The Book of Jihad and Expeditions
32/27. Chapter:
The Prophet (saws) wrote to the Kings of the Kuffar, inviting them to Islam
Sahih Muslim
وَحَدَّثَنَاهُ مُحَمَّدُ بْنُ عَبْدِ اللَّهِ الرُّزِّيُّ، حَدَّثَنَا عَبْدُ الْوَهَّابِ بْنُ عَطَاءٍ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ، عَنِ النَّبِيِّ صلى الله عليه وسلم . بِمِثْلِهِ وَلَمْ يَقُلْ وَلَيْسَ بِالنَّجَاشِي الَّذِي صَلَّى عَلَيْهِ النَّبِيُّ صلى الله عليه وسلم .
The tradition has been narrated on the authority of Anas b. Malik (the same narrator) through a different chain of transmitters, but this version does not mention: " And he was not the Negus for whom the Prophet (ﷺ) had said the funeral prayers."
