عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ خَرَجَ عَلَيْهِمْ وَهُمْ يَذْكُرُونَ الْكَمْأَةَ وَبَعْضُهُمْ يَقُولُ جُدَرِيُّ الْأَرْضِ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ الْكَمْأَةُ مِنَ الْمَنِّ وَمَاؤُهَا شِفَاءٌ لِلْعَيْنِ وَالْعَجْوَةُ مِنَ الْجَنَّةِ وَهِيَ شِفَاءٌ مِنَ السُّمِّ
Sayyiduna Abu Huraira (may Allah be pleased with him) narrates that the Noble Prophet (peace and blessings be upon him) came to his companions while they were discussing mushrooms, and some were saying that it is the smallpox of the earth. This statement reached the Noble Prophet (peace and blessings be upon him), so he said: "Mushroom is from manna, and its water is a cure for the eyes, and the Ajwa date is from Paradise; it is a cure for poison."
