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.  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَتَى بَهِيمَةً فَاقْتُلُوهُ وَاقْتُلُوهَا مَعَهُ قَالَ قُلْتُ لَهُ مَا شَأْنُ الْبَهِيمَةِ قَالَ مَا أُرَاهُ إِلاَّ قَالَ ذَلِكَ أَنَّهُ كَرِهَ أَنْ يُؤْكَلَ لَحْمُهَا وَقَدْ عُمِلَ بِهَا ذَلِكَ الْعَمَلُ  

That the Messenger of Allah ﷺ said: "Whomever you see having relations with an animal then kill him and kill animal." So it was said to Ibn 'Abbas: "What is the case of the animal?" He said: "I did not hear anything from the Messenger of Allah ﷺ about this, but I see that the Messenger of Allah ﷺ disliked eating its meat or using it, due to the fact that such a (heinous) thing has been done with that animal."  

قَالَ رَسُولُ اللَّهِ ﷺ مَنْ وَجَدْتُمُوهُ وَقَعَ عَلَى بَهِيمَةٍ فَاقْتُلُوهُ وَاقْتُلُوا الْبَهِيمَةَ فَقِيلَ لاِبْنِ عَبَّاسٍ مَا شَأْنُ الْبَهِيمَةِ قَالَ مَا سَمِعْتُ مِنْ رَسُولِ اللَّهِ ﷺ فِي ذَلِكَ شَيْئًا وَلَكِنْ أُرَى رَسُولَ اللَّهِ كَرِهَ أَنْ يُؤْكَلَ مِنْ لَحْمِهَا أَوْ يُنْتَفَعَ بِهَا وَقَدْ عُمِلَ بِهَا ذَلِكَ الْعَمَلُ  

That the Messenger of Allah ﷺ said: "Whomever you see having relations with an animal then kill him and kill animal." So it was said to Ibn 'Abbas: "What is the case of the animal?" He said: "I did not hear anything from the Messenger of Allah ﷺ about this, but I see that the Messenger of Allah ﷺ disliked eating its meat or using it, due to the fact that such a (heinous) thing has been done with that animal." (Using translation from Tirmidhī 1455)  

أَنَّ رَسُولَ اللهِ قَالَ «مَنْ وَجَدْتُمُوهُ وَقَعَ عَلَى بَهِيمَةٍ فَاقْتُلُوهُ وَاقْتُلُوا الْبَهِيمَةَ» فَقِيلَ لِابْنِ عَبَّاسٍ مَا شَأْنُ الْبَهِيمَةِ؟ قَالَ مَا سَمِعْتُ عَنْ رَسُولِ اللهِ ﷺ فِي ذَلِكَ شَيْئًا وَلَكِنْ أَرَى رَسُولَ اللهِ ﷺ كَرِهَ أَنْ يُؤْكَلَ مِنْ لَحْمِهَا أَوْ يُنْتَفَعَ بِهَا وَقَدْ عَمِلَ بِهَا ذَلِكَ الْعَمَلَ
