4. A number of our people have narrated from Sahl ibn Ziyad Ahmad ibn Muhammad, from ibn abu Nasr from Ali ibn abu Hamzah from abu Basir who has said the following
“I once asked him (the Imam) (a.s.), about the case of a woman for whom a shadow is prepared while she is in the state of Ihram. He (the Imam) said, ‘Yes, it is permissible.’ I then asked the same about men. He (the Imam) said, ‘Yes, if he suffers from severe headache, but he must pay one mud (a certain measurement) of food as charity for every day.’”
