It was
narrated from Abu Sa`eed and Jabir that the Messenger of Allah
(ﷺ) said:
“Truffles are a type of manna, and their water is a
healing for eye (diseases). And the `Ajwah* are from Paradise, and
they are healing for possession.”**
Another chain from Abu Sa`eed from the Prophet (ﷺ) with similar wording.
