صَحِيحُ مُسْلِمٍ
Sahih Muslim 1774 c
The Book of Jihad and Expeditions
The Prophet (ﷺ) wrote to the Kings of the Kuffar, inviting them to Islam
وَحَدَّثَنِيهِ نَصْرُ بْنُ عَلِيٍّ الْجَهْضَمِيُّ، أَخْبَرَنِي أَبِي، حَدَّثَنِي خَالِدُ بْنُ قَيْسٍ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، وَلَمْ يَذْكُرْ وَلَيْسَ بِالنَّجَاشِيِّ الَّذِي صَلَّى عَلَيْهِ النَّبِيُّ صلى الله عليه وسلم .
It has been narrated on the authority of the same narrator through another chain of transmitters with the same difference in the wording.
