From the Prophet ﷺ, that Kisra sent him a gift so he accepted, and that kings gave him gifts and he accepted them. There is something about this from Jabir. This is a Hasan Gharib Hadith. Thuwair (a narrator in the chain) is Ibn Abi Fakhitah, whose name was Sa'eed bin 'Illaqah, and Thuwair's Kunyah was Abu Jahm.
عَنِ النَّبِيِّ ﷺ أَنَّ كِسْرَى أَهْدَى إِلَيْهِ فَقَبِلَ مِنْهُ وَأَنَّ الْمُلُوكَ أَهْدَوْا إِلَيْهِ فَقَبِلَ مِنْهُمْ قَالَ وَفِي الْبَابِ عَنْ جَابِرٍ وَهَذَا حَدِيثٌ حَسَنٌ غَرِيبٌ وَثُوَيْرٌ هُوَ ابْنُ أَبِي فَاخِتَةَ وَأَبُو فَاخِتَةَ اسْمُهُ سَعِيدُ بْنُ عِلاَقَةَ وَثُوَيْرٌ يُكْنَى أَبَا جَهْمٍ
