Ibn ʿUmar said: "I divorced my wife while she was menstruating. ʿUmar mentioned that to the Prophet . The Prophet ﷺ said, (to my father), "Let your son take her back." I asked (Ibn ʿUmar), "Is such a divorce counted (i.e. as one legal divorce)?" Ibn ʿUmar said, "Of course." Narrated Yunus bin Jubair: Ibn ʿUmar said, "The Prophet ﷺ said to ʿUmar, 'Order him (Ibn ʿUmar) to take her back.' " I asked, "Is such a divorce counted (as one legal divorce)?" Ibn ʿUmar said, "What do you think if someone becomes helpless and foolish?"
