وَعَنْ سَعِيدِ بْنِ زَيْدٍ رَضِيَ اللَّه عَنْهُ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: الْكَمْأَةُ مِنَ الْمَنِّ، وَمَاؤُهَا شِفَاءٌ لِلْعَيْنِ ((مُتَّفَقٌ عَلَيْهِ)).
Sa'id bin Zaid (May Allah be pleased with him) reported: I heard the Messenger of Allah (ﷺ) saying, "Truffle (edible fungus) is a species of Al-Manna and their water cures eye diseases." [Al-Bukhari and Muslim]
