Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) narrates that the Messenger of Allah (peace be upon him) said: "O group of women, when men go into prostration, guard your gaze." Imam Abu Sufyan says that I asked Abdullah bin Abi Bakr, "For what reason was this command given?" He replied, "Because of the tightness and shortness of the lower garments and sheets." The Imam, through his teacher Abu Yahya Muhammad bin Abdur Rahim, presents a similar narration that the Prophet (peace be upon him) said: "Guard your gaze from the private parts of men."
