Narrated 'Ali:

"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.'"

حَدَّثَنَا هَنَّادٌ، حَدَّثَنَا عَبْدَةُ، عَنْ سَعِيدٍ، عَنْ قَتَادَةَ، عَنْ جُرَىِّ بْنِ كُلَيْبٍ النَّهْدِيِّ، عَنْ عَلِيٍّ، قَالَ نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يُضَحَّى بِأَعْضَبِ الْقَرْنِ وَالأُذُنِ . قَالَ قَتَادَةُ فَذَكَرْتُ ذَلِكَ لِسَعِيدِ بْنِ الْمُسَيَّبِ فَقَالَ الْعَضْبُ مَا بَلَغَ النِّصْفَ فَمَا فَوْقَ ذَلِكَ .

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ .
