It is narrated from Hazrat Abu Saeed Khudri (may Allah be pleased with him) that once the wife of Safwan bin Mu'attal came to the service of the Prophet (peace and blessings of Allah be upon him), while we were present there. She said, "O Messenger of Allah (peace and blessings of Allah be upon him)! When I pray, my husband Safwan bin Mu'attal beats me, and when I fast, he makes me break it, and he himself does not pray Fajr until the sun rises." Safwan was also present there. The Prophet (peace and blessings of Allah be upon him) asked him about this, so he said, "O Messenger of Allah (peace and blessings of Allah be upon him)! As for what she said, that when she prays, I beat her, it is because she recites two surahs in one rak'ah. I forbade her from this." The Prophet (peace and blessings of Allah be upon him) said, "One surah is sufficient for all people." "As for her saying that I make her break her fast, she keeps voluntary fasts. I am a young man and I cannot be patient." On that day, the Prophet (peace and blessings of Allah be upon him) said, "No woman should keep a voluntary fast without her husband's permission." "And as for her saying that I do not pray Fajr until the sun rises, it is well known among our household that we only wake up after the sun has risen." The Prophet (peace and blessings of Allah be upon him) said, "Whenever you wake up, perform the prayer."
