From Mujahid from Ibn 'Abbas who said: "The Messenger of Allah (ﷺ) prohibited instigating fights between beasts."
Jami` at-Tirmidhi Book 23, Hadith 40
← Previous Hadith That the Messenger of Allah (ﷺ) said: "Hearing and obeying is required from every Muslim man - in what he like and what he dislikes - as long as he is not ordered with disobedience. If he is ordered with disobedience, then no hearing or obeying is required of him."

There are narrations on this topic from 'Ali, 'Imran bin Husain, and Al-Hakam bin 'Amr Al-Ghifari. This Hadith is Hasan Sahih.

Jami` at-Tirmidhi Book 23, Hadith 39 Next Hadith → "The Prophet (ﷺ) prohibited instigating fights between beasts." And he did not mention "from Ibn 'Abbas" in it.

It is said that this is more correct that the (previous) narration of Qutbah.
