مُحَمَّدُ بْنُ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ عَبْدِ الرَّحْمَنِ بْنِ حَمَّادٍ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ عَنْ مُحَمَّدِ بْنِ الْفَيْضِ قَالَ قُلْتُ لِأَبِي عَبْدِ اللَّهِ (عليه السلام) يَمْرَضُ مِنَّا الْمَرِيضُ فَيَأْمُرُ الْمُعَالِجُونَ بِالْحِمْيَةِ فَقَالَ لَكِنَّا أَهْلُ بَيْتٍ لَا نَحْتَمِي إِلَّا مِنَ التَّمْرِ وَ نَتَدَاوَى بِالتُّفَّاحِ وَ الْمَاءِ الْبَارِدِ قُلْتُ وَ لِمَ تَحْتَمُونَ مِنَ التَّمْرِ قَالَ لِأَنَّ نَبِيَّ اللَّهِ حَمَى عَلِيّاً (عليه السلام) مِنْهُ فِي مَرَضِهِ.
441. Muhammad Bin Yahya, from Ahmad Bin Muhammad Bin Isa, from Abdul Rahman Bin Hammaad, from Muhammad Bin Is’haq, from Muhammad Bin Al-Fayz who said, who has narrated the following: I said to Abu Abdullah , ‘When one of us becomes ill, the healers order us to go on a diet’. So he  said: ‘But, the People  of the Household, we  do not stay away except from the dates, and we  cure by the apple and the cold water’. I said, ‘And why do you  keep away from the dates?’ He  said: ‘Because the Prophet ﷺ of Allah (azwj) kept Ali  away from it during his  illness’.
