Among those who will occupy the worst position in the sight of Allah on the Day of Resurrection is the man who has intercourse with his wife and she with him, and then he spreads her secret.
One of the Prophet's Sahabas narrated, Allah's Messenger (peace be on him) led us in prayer, and when he had finished he turned toward us and said, 'Remain seated. Is there among you the man who comes to his wife, closes the door, and draws the curtain, and then goes out and speaks about it, saying, "I did this and I did that with my wife?" They remained silent. Then he turned toward the women and asked, 'Is there among you one who tells about such things?' A girl raised herself on her knees so that the Messenger of Allah (peace be on him) could see her and listen to what she said. She said, 'Yes, by Allah, the men talk about it and the women do, too.' Then the Prophet (peace be on him) said, 'Do you know what those who do this are like? The ones who do this are like a male and female devil who meet each other in the road and satisfy their desire while the people look on.
This emphatic way of expressing the matter should be sufficient to turn the Muslim away from such ill-considered and degraded behavior, which would make him or her resemble a devil!.
