عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ أَبِي عَبْدِ اللَّهِ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ عَنْ مُحَمَّدِ بْنِ الْفُضَيْلِ عَنْ عَبْدِ الرَّحْمَنِ بْنِ زَيْدٍ عَنْ أَبِي عَبْدِ اللَّهِ ( عليه السلام ) قَالَ
قَالَ رَسُولُ اللَّهِ ( صلى الله عليه وآله ) الْكَمْأَةُ مِنَ الْمَنِّ وَ الْمَنُّ مِنَ الْجَنَّةِ وَ مَاؤُهَا شِفَاءٌ لِلْعَيْنِ .
2. A number of our people have narrated from Ahmad ibn abu ‘Abd Allah from Muhammad ibn Ali from Muhammad ibn al-Fudayl from ‘Abd al-Rahman ibn Zayd who has said the following: “Abu ‘Abd Allah 
, has said that the Messenger of Allah, O Allah, grant compensation to Muhammad and his family worthy of their services to Your cause, has said,
‘The truffle is from Manna (honeydew, a kind of tree sap) which is from paradise and its water is cure for the eye.’”
