(28) باب فَضْلِ الْكَمْأَةِ وَمُدَاوَاةِ الْعَيْنِ بِهَا
Sa'id b. Zaid reported:
I heard Allah's Messenger (ﷺ) as saying: Truffles are a kind of blessing and their juice is a medicine for the eyes. Shu'ba said: When Hakam narrated this hadith to me, I did not deem it as a Munkar hadith because of the narration of Abd al-Malik.
