Abu Ubaydah bin Abdullah bin Mas'ud narrates: Sayyiduna Uthman (may Allah be pleased with him) sent (someone) to my father (Sayyiduna Ibn Mas'ud, may Allah be pleased with him) to ask him about this issue. My father said: "How can a hypocrite give a fatwa?" Sayyiduna Uthman (may Allah be pleased with him) said: We seek refuge in Allah from your being a hypocrite, and we seek refuge in Allah from calling you a hypocrite, and we commend you to Allah's protection from an issue like this arising in Islam and then you dying without having made it clear. My father said: "My view is that he (the husband) has more right to her until she takes the ritual bath from the third menstrual period and the prayer becomes lawful for her." The narrator said: I know that Sayyiduna Uthman (may Allah be pleased with him) adopted this very view.
