٦ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ عَلِيِّ بْنِ الْحُسَيْنِ بْنِ عَبْدِ رَبِّهِ قَالَ قُلْتُ لَهُ مَا تَقُولُ فِي الْفَصِّ يُتَّخَذُ مِنْ حِجَارَةِ زُمُرُّدٍ قَالَ لاَ بَأْسَ بِهِ وَلَكِنْ إِذَا أَرَادَ الاسْتِنْجَاءَ نَزَعَهُ.
6. Muhammad ibn Yahya has narrated from Muhammad ibn Ahmad from Muhammad ibn ‘Isa from Ali ibn al-Husayn ibn ‘Abd Rabbihi who has said the following: “I once asked him (the Imam), ‘Is it permissible to wear a ring with a stone of Emerald?’ He (the Imam) replied, ‘It is not harmful but during washing one’s self after using the toilet, one should remove it.’”
