Umair bin Ishaq says that I was with Hasan bin Ali (may Allah be pleased with him), when Sayyiduna Abu Hurairah (may Allah be pleased with him) met us and said: Come here, so that I may kiss you at the place where I saw the Messenger of Allah (peace and blessings be upon him) kissing you. Then he lifted his shirt and kissed his navel.

Sayyiduna Muawiyah bin Haydah (may Allah be pleased with him) says: I asked, "O Messenger of Allah! From whom among our private parts (i.e., the areas that must be covered) can we see, and from whom can we not see?" The Prophet (peace and blessings be upon him) said: "Protect your private parts from everyone except your wife and your slave woman." Muawiyah says: I asked, "O Messenger of Allah! What if people are together with each other?" The Prophet (peace and blessings be upon him) said: "If you are able that no one sees (your private parts), then let no one see them." Muawiyah says: I asked, "What if a person is alone?" The Prophet (peace and blessings be upon him) replied: "Allah is more deserving that one should feel shy before Him." According to one narration (to explain the matter), the Noble Prophet (peace and blessings be upon him) raised his hand and placed it on his private part.

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: A man should not look at the private parts of another man, nor should a woman look at the private parts of another woman, and a man should not lie with another man under a single garment, nor should a woman lie with another woman under a single garment.

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: When Musa bin Imran, peace be upon him, intended to enter the water, he would not remove his garment until he had concealed his private parts in the water.

Sayyidah Aisha (may Allah be pleased with her) says: I have never seen the private part of the Noble Prophet (peace and blessings be upon him).

It is narrated from Sayyidah Aisha (may Allah be pleased with her) that the Noble Prophet (peace and blessings be upon him) said: The prayer of an adult woman is not accepted without a head covering.

Muhammad bin Sirin narrates that Sayyida Aisha (may Allah be pleased with her) came to Safiyyah, the mother of Talha al-Talhat, and saw some of her girls who had reached puberty but were praying without head coverings. Muhammad says: Sayyida Aisha (may Allah be pleased with her) said: None of these girls should pray without a head covering, because there was a girl under my care, and when the Messenger of Allah (peace and blessings be upon him) came to me, he threw his cloak towards me and said: Distribute this cloak between this girl and the girls in the lap of Umm Salamah, because I think they have reached puberty.

It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: A man should not perform prayer in a single garment in such a way that none of it covers his shoulders.

And it is also narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: When any one of you prays in a single garment, he should throw its two ends over his shoulders in opposite directions.

Sayyiduna Kaysan (may Allah be pleased with him) narrates that he saw the Messenger of Allah (peace and blessings be upon him) coming out from the place of kitchens and going to the place of the well. He (peace and blessings be upon him) was wearing only an izar (lower garment) and did not have an upper sheet on. The Prophet (peace and blessings be upon him) saw some slaves praying near the place of the well, so he also took off his izar and used it as a covering, and then performed two rak‘ahs. I do not know whether it was Zuhr or ‘Asr.
