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.’”
