وَقَالَ مُحَمَّدٌ: يَجِبُ فِي الصَّيْدِ النَّظِيرُ فِيمَا لَهُ نَظِيرٌ.
Translation: Muhammad holds that when the hunted animal has a corresponding livestock equivalent, that equivalent is owed.
This differs from the primary value-appraisal framework just stated for Abu Hanifah and Abu Yusuf. Muhammad treats a recognized domestic-animal analogue as the required equivalent where one exists.
Nazir denotes the juristically identified counterpart, not simply anything with an approximately similar price.
