فَجَزَاءٌ مِثْلُ مَا قَتَلَ مِنَ النَّعَمِ
Compensation equivalent to what was killed, from livestock. (Qurʾān 5:95, relevant excerpt)
The term mithl (equivalent) raises a juristic question: does equivalence refer primarily to similarity in physical form, or to equality of value?
For some hunted animals, resemblance to a livestock animal can be proposed; in other applications, monetary equivalence is considered the governing measure.
Different understandings produce different methods of fulfilling the legal duty, so the interpreter must weigh the relevant arguments.
