Ali ibn Asbat reported from his uncle Ya’qub Al-Ahmar, from Abu Basir, who narrated: Abu Abdillah عليه السلام said: "Any woman who was observing i'tikaf (spiritual retreat) and then became prohibited from prayer (due to menstruation) and left the mosque, if she becomes pure, it is not appropriate for her husband to have intercourse with her until she returns to the mosque and completes her i'tikaf."
