"The Messenger of Allah ﷺ prohibited that an animal with a A'dab (stump) horn or ear should be slaughtered as a sacrifice." Qatadah (one of the narrators) said: "So I mentioned this to Sa'eed bin Al-Musayyab and he said: 'The A'dab is that which equals or more than that.'"  

نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يُضَحَّى بِأَعْضَبِ الْقَرْنِ وَالأُذُنِ قَالَ قَتَادَةُ فَذَكَرْتُ ذَلِكَ لِسَعِيدِ بْنِ الْمُسَيَّبِ فَقَالَ الْعَضْبُ مَا بَلَغَ النِّصْفَ فَمَا فَوْقَ ذَلِكَ  

I heard Jurayy bin Kulaib say: I heard ‘Ali ؓ say: The Messenger of Allah ﷺ forbade (sacrificing) an animal that had lost most of its horn or ear. Qatadah said: I asked Saʿeed bin Al-Musayyab: What does lost most of its ear mean? He said: If it has lost half or more of it.  

سَمِعْتُ عَلِيًّا يَقُولُ نَهَى رَسُولُ اللهِ ﷺ عَنْ عَضَبِ الْقَرْنِ وَالْأُذُنِ قَالَ قَتَادَةُ فَسَأَلْتُ سَعِيدَ بْنَ الْمُسَيِّبِ قَالَ قُلْتُ مَا عَضَبُ الْأُذُنِ؟ فَقَالَ إِذَا كَانَ النِّصْفَ أَوِ اكْثَرَ مِنْ ذَلِكَ  

"The Messenger of Allah ﷺ prohibited that an animal with a A'dab (stump) horn or ear should be slaughtered as a sacrifice." Qatadah (one of the narrators) said: "So I mentioned this to Sa'eed bin Al-Musayyab and he said: 'The A'dab is that which equals or more than that.'" (Using translation from Tirmidhī 1504)   

«أَنَّ النَّبِيَّ ﷺ نَهَى أَنَّ يُضَحَّى بِأَعْضَبِ الْقَرْنِ وَالْأُذُنِ» قَالَ قَتَادَةُ وَذَكَرْتُ ذَلِكَ لِسَعِيدِ بْنِ الْمُسَيَّبِ قَالَ «الْعَضْبُ النِّصْفُ فَمَا فَوْقَ ذَلِكَ»  

[Machine] Ali heard the Prophet ﷺ saying that he forbade sacrificing parts of the ear and horn. Qatadah said, "I asked Sa'id ibn al-Musayyib about the 'adhab (part of an animal's ear and horn) and he said, 'Half is enough, and anything beyond that is excess.'"  

سَمِعَ عَلِيًّا ؓ يَقُولُ نَهَى رَسُولُ اللهِ ﷺ أَنْ يُضَحَّى بِعَضْبَاءِ الْأُذُنِ وَالْقَرْنِ قَالَ قَتَادَةُ وَسَأَلْتُ سَعِيدَ بْنَ الْمُسَيِّبِ عَنِ الْعَضَبِ فَقَالَ النِّصْفُ فَمَا زَادَ
