Bayhaqi 16214 — Head wounds less than the mudihah

Sayyiduna Zayd bin Thabit (may Allah be pleased with him) says: For a wound from which blood comes out (damiyah) there is one camel; for one that cuts into the flesh (badi'ah) two camels; for one in which the flesh becomes exposed (mutalahimah) three camels; for a head wound that reaches the thin membrane over the bone (simhaq) four camels; and for a bone-exposing wound in which the bone becomes visible (mudihah) five camels.
The Shaykh said: Muhammad bin Rashid, even though we narrate his hadith because senior narrators reported from him, is not one whose solitary narrations constitute a proof.
It is also reported from Sayyiduna Ali (may Allah be pleased with him) that for the simhaq there are four camels; this is narrated from al-Hakam bin Utaybah from Ali, and similarly from Jabir al-Ju'fi from Abdullah bin Nujayy from Ali. The first is munqati' (broken) and the second is munqati' (broken). Moreover, if this narration is authentic, it is understood to mean that they ruled on wounds less than the mudihah by an estimated compensation (hukumah) that reached this amount. And Allah knows best.
