3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ مُعَاوِيَةَ بْنِ عَمَّارٍ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنِ الْمُحْرِمِ تَطُولُ أَظْفَارُهُ أَوْ يَنْكَسِرُ بَعْضُهَا فَيُؤْذِيهِ ذَلِكَ قَالَ لا يَقُصُّ مِنْهَا شَيْئاً إِنِ اسْتَطَاعَ فَإِنْ كَانَتْ تُؤْذِيهِ فَلْيَقُصَّهَا وَلْيُطْعِمْ مَكَانَ كُلِّ ظُفُرٍ قَبْضَةً مِنْ طَعَامٍ.
3. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Mu‘awiyah ibn ‘Ammar who has said the following: “I once asked abu ‘Abd Allah (a.s.), about a man who is in the state of Ihram and his nails grow tall or break and it annoys him. He (the Imam) said, ‘He must not cut anything if he can; but if it upsets him, he can cut them and for every nail he must feed a handful of (one meal) food.’”
