The man who had committed the act with her stood up and said: "O Messenger of Allah, I am the one who did it with her." He said to her: "Go, for Allah has forgiven you." And he said to the man a kind word, and concerning the man who had committed the act with her, he said: "Stone him." And he said: "He has made a repentance such that if the people of Medina had made it, it would have been accepted from them." (1)

This is a good, rare, and authentic hadith. 'Alqamah ibn Wa'il ibn Hujr heard from his father, and he is older than 'Abd al-Jabbar ibn Wa'il, and 'Abd al-Jabbar ibn Wa'il did not hear from his father.

23 - Chapter: What has been reported concerning one who commits bestiality

1521 - Muhammad ibn 'Amr al-Sawwaq narrated to us, he said: 'Abd al-'Aziz ibn Muhammad narrated to us, from 'Amr ibn Abi 'Amr, from 'Ikrimah, from Ibn 'Abbas, who said: The Messenger of Allah, peace and blessings be upon him, said: "Whoever you find having committed an act with an animal, kill him and kill the animal." It was said to Ibn 'Abbas: "What is the matter with the animal?" He said: "I did not hear anything from the Messenger of Allah, peace and blessings be upon him, concerning that, but I think the Messenger of Allah, peace and blessings be upon him, disliked that its flesh be eaten or that it be benefited from, when such an act had been done with it."

(1) Its chain is good; Simak ibn Harb is truthful and good in hadith, and the rest of its narrators are trustworthy. It was also recorded by Abu Dawud (4379), and it is in the Musnad (27240).
(2) Weak. 'Amr ibn Abi 'Amr, the freed slave of al-Muttalib — although Ahmad, Abu Zur'ah, Abu Hatim, and al-'Ijli declared him trustworthy — Ibn Ma'in, al-Nasa'i, and 'Uthman al-Darimi weakened him due to his narration of this hadith from 'Ikrimah. Al-'Ijli said: They objected to his hadith of the animal. Al-Bukhari said: I do not know =
