Chapter 90 | Use of Shadow in the State of al-’Ihram
12ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ سَهْلِ بْنِ زِيَادٍ عَنْ بَكْرِ بْنِ صَالِحٍ قَالَ كَتَبْتُ إِلَى أَبِي جَعْفَرٍ (عَلَيْهِ السَّلاَم) أَنَّ عَمَّتِي مَعِي وَهِيَ زَمِيلَتِي وَالْحَرُّ تَشْتَدُّ عَلَيْهَا إِذَا أَحْرَمَتْ فَتَرَى لِي أَنْ أُظَلِّلَ عَلَيَّ وَعَلَيْهَا فَكَتَبَ (عَلَيْهِ السَّلاَم) ظَلِّلْ عَلَيْهَا وَحْدَهَا.
12. A number of our people have narrated from Sahl ibn Ziyad from baker ibn Salih who has said the following: “I once wrote to abu Ja‘far , that my aunt who is my travel-mate and the heat is severe for her while she is in the state of Ihram; if I can provide shadow for her and for myself. He (the Imam) wrote, ‘You can provide shadow just for her alone.’”
