Zayd bin Thabit (may Allah be pleased with him) said: For hair, as long as it does not grow back, there is the diyah (blood money). This is munqati' (has a broken chain). And Zayd (may Allah be pleased with him) said: For the eyebrow there is one third of the diyah. And there is also a narration from Zayd and Ali (may Allah be pleased with them both) that there is the diyah for it.
Al-Hajjaj bin Artah is not used as evidence, and what is narrated from Ali and Zayd (on this) is not established.
