عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُحَمَّدِ بْنِ أَبِي حَمْزَةَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ وَ ابْنِ أَبِي عُمَيْرٍ عَنْ عُمَرَ بْنِ أُذَيْنَةَ قَالَ شَكَا رَجُلٌ إِلَى أَبِي عَبْدِ اللَّهِ ( عليه السلام ) شُقَاقاً فِي يَدَيْهِ وَ رِجْلَيْهِ فَقَالَ لَهُ خُذْ قُطْنَةً فَاجْعَلْ فِيهَا بَاناً وَ ضَعْهَا فِي سُرَّتِكَ فَقَالَ إِسْحَاقُ بْنُ عَمَّارٍ جُعِلْتُ فِدَاكَ يَجْعَلُ الْبَانَ فِي قُطْنَةٍ وَ يَجْعَلُهَا فِي سُرَّتِهِ فَقَالَ أَمَّا أَنْتَ يَا إِسْحَاقُ فَصُبَّ الْبَانَ فِي سُرَّتِكَ فَإِنَّهَا كَبِيرَةٌ قَالَ ابْنُ أُذَيْنَةَ لَقِيتُ الرَّجُلَ بَعْدَ ذَلِكَ فَأَخْبَرَنِي أَنَّهُ فَعَلَهُ مَرَّةً وَاحِدَةً فَذَهَبَ عَنْهُ .
2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Muhammad ibn abu Hamzah from Ishaq ibn ‘Ammar and Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah who has said the following: “Once, a man complained before abu ‘Abd Allah , about cracks in his hands and feet. He (the Imam) said, ‘Take a piece of cotton, place frankincense oil in it and apply it in your belly button.’ Ishaq ibn ‘Ammar has said that I said, ‘I pray to Allah to keep my soul in service for your cause, frankincense oil in cotton, then in his belly button?’ He (the Imam) said, ‘O Ishaq, to pour frankincense oil in your belly button it is a great task.’ Ibn ‘Udhaynah has said, ‘Thereafter I met the man. He informed me that he followed the instruction only once and his problems went away.’”
