Narrated Qatadah:
I asked Sa'id b. al-Musayyab: What is meant by animal with a slit ear and broken horn ? He replied: Half and more than half.

حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، حَدَّثَنَا هِشَامٌ، عَنْ قَتَادَةَ، قَالَ قُلْتُ لِسَعِيدِ بْنِ الْمُسَيَّبِ مَا الأَعْضَبُ قَالَ النِّصْفُ فَمَا فَوْقَهُ .
