2ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الصَّائِمِ يَصُبُّ فِي أُذُنِهِ الدُّهْنَ قَالَ لا بَأْسَ بِهِ.
2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Hammad who has said the following: “I once asked abu ‘Abd Allah , ‘Can a fasting man apply oil to his ears?’ He (the Imam) said, ‘It is not harmful.’”
