It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the wife of Sayyiduna Safwan bin Mu'attal (may Allah be pleased with him) came to the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! The situation with my husband, Sayyiduna Safwan bin Mu'attal (may Allah be pleased with him), is that when I pray, he beats me; when I fast, he makes me break my fast; and he performs the Fajr prayer after sunrise. At that time, Sayyiduna Safwan was also present there. When the Prophet (peace and blessings be upon him) asked him about his wife's complaints, he said: O Messenger of Allah! As for her saying that I beat her when she prays, the matter is that she recites two long surahs, whereas I have forbidden her from that. The Prophet (peace and blessings be upon him) said: Even if one surah is recited, it is sufficient for the people. She then said: As for her saying that I make her break her fast when she is fasting, the reason is that I am a young man and I cannot control myself. Upon hearing this, the Prophet (peace and blessings be upon him) said that day: No woman should ever observe (optional) fast without her husband's permission. And as for her saying that I perform the Fajr prayer after sunrise, the explanation is that we are people of this tribe who cannot wake up before the sun rises. The Prophet (peace and blessings be upon him) said: Whenever you wake up, perform the prayer at that time. In another narration: Sayyiduna Safwan (may Allah be pleased with him) said: Indeed, my head remains heavy, and our whole family is such that it is well known about us that our heads remain heavy. The Prophet (peace and blessings be upon him) said: Whenever you wake up, perform the prayer at that time.
