Will a woman sin if she does not accept the invitation of her Muslim sister with her husband's consent?
Is accepting the invitation, visiting the sick and other Muslims restricted to men only? Does this include women, after acquiring the husband's permission?
Acceptance of a woman the invitation of her Muslim sister to a Walimah (wedding dinner) is Wajib (obligatory), in which case she sins if she refuses to attend, as long as her husband gives her the permission to go, and as long as this Walimah does not include any Munkar (that which is unacceptable or disapproved of by Islamic law and Muslims of sound intellect), or include a Munkar that could be changed. Otherwise, she should not accept the invitation and there is no sin upon her because of this. As for accepting the invitation, and visiting the sick, it is not restricted to men. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
