"Shall I not tell you about the Prophet and I?" We said: "Yes." She said: "When it was my night when he" -meaning the Prophet- "was with me, he came in, placed his shoes by his feet, lay down his Rida' (upper garment), and spread the edge of his Izar (lower garment) on his bed. As soon as he thought that I had gone to sleep, he put his shoes on slowly, and picked up his Rida' slowly. Then he opened the door slowly, went out and shut it slowly. I put my garment over my head, covered myself and put on my Izar (lower garment), and I set out after him until he came to Al-Baqi', raised his hands three times and stood there for a long time. Then he left and I left, he hurried and I hurried, he ran and I ran, and I got there before him and entered (the house). I had only just laid down when he came in and said: 'O 'Aishah, why are you out of breath?' She said: 'No.' He said: 'Either you tell me or Allah, the All-Aware, All-Knowing, will tell me.' I said: 'O Messenger of Allah, may my father and mother be sacrificed for you;' and I told him the story. He said: 'You were the black shape I saw in front of me?' I said: 'Yes.'" She said: "He gave me a shove in the chest that hurt me and said: 'You thought that Allah and His Messenger would be unfair to you.' She said: 'Whatever people conceal, Allah knows it.' He said: 'Yes.' He said: 'Jibril came to me when you saw (me leave) but he did not enter upon you because you have taken off your garments. So he called me but he concealed himself from you, and I answered him, but I concealed it from you. I thought that you had gone to sleep and I did not want to wake you, and I was afraid that you would feel lonely. He told me to go to Al-Baqi' and pray for forgiveness for them.'" 'Asim reported it from 'Abdullah bin 'Amir, from 'Aishah, with a wording different from this.
Sunan an-Nasa'i Book 36, Hadith 26
"Why don't you pledge to me upon that which the women have pledged: That you will not associate anything with Allah, that you will not steal, that you will not have unlawful sexual relations, that you will not utter slander, fabricating from between your hands and feet, and that you will not disobey me in goodness (Ma'ruf)?" We said: "yes, O Messenger of Allah." So we gave him our pledge, on that basis. The Messenger of Allah said: "Whoever commits any of these actions after that, and is punished, that will be an expiation. Whoever is not punished, then his affair is up to Allah; if He wills, He will forgive him, and if He wills, He will punish him."
