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.
Jami` at-Tirmidhi Book 21, Hadith 37
← Previous Hadith "The Messenger of Allah (ﷺ) used to go to battle with Umm Sulaim, and other women with her, from the Ansar, who would give water and attend to the wounded."

There is something on this topic from Ar-Rabi' bin Mu'awwidh. This Hadith is Hasan Sahih.

Jami` at-Tirmidhi Book 21, Hadith 36 Next Hadith → That he gave the Prophet (ﷺ) a gift or a camel, so the Prophet (ﷺ) said: "Have you accepted Islam?" He said: "No." He said: "Then I have been prohibited from the Zabd (gift) of the idolaters."

This Hadith is Hasan Sahih. And the meaning of his saying: "I haven been prohibited from the Zabd (gifts) of the idolaters" is their gifts.

It has been reported about the Messenger (ﷺ) that he used to accept the gifts of the idolaters while a dislike for that is mentioned in this Hadith.

And the implication is that this was after he used to accept from them, and then he later forbade their gifts.
