A wife visiting her brother-in-law during his illness
Is it permissible for my mother to visit my uncle during his illness and talk to him?
There is no blame on your mother if she visits your uncle during his illness, provided that (Part No. 17; Page No. 406) there is no Khulwah (being alone with a member of the opposite sex) between them. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
