وَعَن سعيد بنِ زيدٍ
قَالَ: قَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «الْكَمْأَةُ مِنَ الْمَنِّ وَمَاؤُهَا شِفَاءٌ لِلْعَيْنِ» وَفِي رِوَايَةٍ لِمُسْلِمٍ: «مِنَ الْمَنِّ الَّذِي أنزلَ اللَّهُ تَعَالَى على مُوسَى عَلَيْهِ السَّلَام»
The Prophet (sallallahu alayhi wa sallam) said:, “Truffles are a kind of manna, and their juice is a medicine for the eye.” (Bukhari and Muslim.) A version by Muslim has, “a kind of the manna which God most high sent down to Moses.”
