Hadith 4464
Narrated Abdullah ibn Abbas: The Prophet ﷺ said: If anyone has sexual intercourse with an animal, kill him and kill it along with him. I (Ikrimah) said: I asked him (Ibn Abbas): What offence can be attributed to the animal/ He replied: I think he (the Prophet) disapproved of its flesh being eaten when such a thing had been done to it. Abu Dawud said: This is not a strong tradition.
Hadith 4465
Asim reported from Abu Razin on the authority of Ibn Abbas saying: There is no prescribed punishment for one who has sexual intercourse with an animal. Abu Dawud said: Ata is also so. Al Hakam said: I think he should be flogged, but the number should not reach the one of the prescribed punishment. Al-Hasan said: He is like a fornicator. Abu Dawud said: THe tradition of Asim proves the tradition of Amr bin Abi Amr as weak.
