Chapter: Use of Shadow in the State of al-’Ihram ِنْ أَصْحَابِنَا عَنْ أَحْ٠َاعِيلَ بْنِ بَزِيعٍ قَالَ كَتَبْتُ إِلَى الرِّضَا (عَلَيْهِ السَّلاَ٠) هَلْ يَجُوزُ لِلْ٠ْشِيَ تَحْتَ ظِلِّ الْ٠ِلِ فَكَتَبَ نَعَ٠ْ قَالَ وَسَأَلَهُ رَجُلٌ عَنِ الظِّلالِ لِلْ٠ْسٍ وَأَنَا أَسْ٠َرَهُ أَنْ يَفْدِيَ شَاةً وَيَذْبَحَهَا بِ٠5.

A number of our people have narrated from Ahmad ibn Muhammad from ‘Isma‘il ibn Bazi’ who has said the following: “I wrote to al-Rida’ (a.s.), and asked if it is permissible to walk in the shadow of the carriage on camel back.

He (the Imam) wrote back, ‘Yes, it is permissible.’ Another man had asked about preparing a shadow for one in the state of Ihram because of rain or sun and I was listening, he (the Imam) commanded him to pay a ransom of one sheep to be slaughtered in Mina.” صحيح - Allamah Baqir al-Majlisi (Mirʾāt al-ʿUqūl fī Sharḥ Akhbār Āl al-Rasūl (7/303))
