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 ‏.‏

'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. Translation Not Available
