٤ـ عَلِيُّ بْنُ مُحَمَّدٍ عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ إِسْمَاعِيلَ بْنِ مِهْرَانَ قَالَ كَتَبْتُ إِلَى الرِّضَا (عَلَيْهِ الْسَّلام) أَسْأَلُهُ عَنْ حَدِّ الْوَجْهِ فَكَتَبَ مِنْ أَوَّلِ الشَّعْرِ إِلَى آخِرِ الْوَجْهِ وَكَذَلِكَ الْجَبِينَيْنِ.
4. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from ’Isma‘il ibn Mehran who has said the following: “I wrote to al-Rida , and asked him about the limits of the area of the face. He wrote this back to me, ‘It is from the hairline down to the end and (beginning of) both brows.’”
