From Hud bin 'Abdullah bin Sa'd, from his grandfather Mazidah, who said: "The Messenger of Allah (ﷺ) on the Day of the Conquest and there was gold and silver on his sword." Talib said: "So I asked him about the silver and he said: 'The hand-guard of his sword was of silver.'"

There is something on this topic form Anas. This Hadith is Hasan Gharib. Hud's (great) grandfather's name is Mazidah Al-'Asari.
Jami` at-Tirmidhi Book 23, Hadith 21
← Previous Hadith "Indeed we saw the day of Hunain, and indeed the two armies fled from the Messenger of Allah (ﷺ), and there did not remain one hundred men with the Messenger of Allah (ﷺ)."

This Hadith is Hasan Gharib as a narration of 'Ubaidullah. We do not know of it except from this route.

Jami` at-Tirmidhi Book 23, Hadith 20 Next Hadith → "The hand-guard on the sword of the Messenger of Allah (ﷺ) was made from silver."

This Hadith is Hasan Gharib. This is how it has been reported from Hamam from Qatadah from Anas. While some of them reported it from Qatadah, from Sa'eed bin Abu Al-Hasan who said: "The hand-guard on the sword of Messenger of Allah (ﷺ) was made from silver."
