The Messenger of Allah (ﷺ) was present with a she-mule which he rode, so Ali said: If we made asses cover mares we would have animals of this type. The Messenger of Allah (ﷺ) said: Only those who do not know do that.
Sunan Abi Dawud Book 15, Hadith 89
← Previous Hadith Jabir reported the Prophet (ﷺ) as saying when an ass which had been branded on its face passed him. Did it not reach you that I cursed him who branded the animals on their faces or struck them on their faces. So he prohibited it.

Sunan Abi Dawud Book 15, Hadith 88 Next Hadith → ‘Abd Allah bin Ja’far said “When the Prophet (ﷺ) arrived after a journey, we were taken for his reception. Any of us who met him first he lifted him in front of him. As I was the first to meet him, he lifted me in front of him. Then Hasan or Hussain was brought to him and he set him behind him. We the entered Madeenah and we (were) riding so (three on one beast).”
