Sunan Abi Dawud, Hadith 4450 ⓘ
'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 b. Abi 'Amr as weak.
حَدَّثَنَا أَحْمَدُ بْنُ يُونُسَ، أَنَّ شَرِيكًا، وَأَبَا الأَحْوَصِ، وَأَبَا، بَكْرِ بْنَ عَيَّاشٍ حَدَّثُوهُمْ عَنْ عَاصِمٍ، عَنْ أَبِي رَزِينٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ لَيْسَ عَلَى الَّذِي يَأْتِي الْبَهِيمَةَ حَدٌّ . قَالَ أَبُو دَاوُدَ كَذَا قَالَ عَطَاءٌ وَقَالَ الْحَكَمُ أَرَى أَنْ يُجْلَدَ وَلاَ يَبْلُغَ بِهِ الْحَدَّ . وَقَالَ الْحَسَنُ هُوَ بِمَنْزِلَةِ الزَّانِي . قَالَ أَبُو دَاوُدَ حَدِيثُ عَاصِمٍ يُضَعِّفُ حَدِيثَ عَمْرِو بْنِ أَبِي عَمْرٍو .
