Telling what a man does with his wife and a woman with her husband

Sayyiduna Salman (may Allah be pleased with him) said: If I were to be alone with my wife, close the door, let down the curtain and then describe these matters, then telling people about them would be the same to me as people watching me in that state.

It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Among the worst people in the sight of Allah Almighty on the Day of Resurrection will be the man who goes in to his wife and she to him, and then he spreads her secret."

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "How can it be right that one of you men tells people the details of his intimacy with his wife, or that one of you women tells people the details of her intimacy with her husband?" At this a black woman said: "O Messenger of Allah, indeed the men do this and the women do this too." The Prophet (peace and blessings be upon him) said: "Let me explain this to you with an example. Its likeness is that of a male devil who meets a female devil and has intercourse with her in the road while people are watching; he fulfils his need of her while people are watching."

Mujahid (may Allah have mercy on him), explaining the verse of the Qur'an {And when they pass by ill speech, they pass by with dignity} [Al-Furqan: 72], said that when they mention marital intimacy, they do so by way of allusion.
