It is forbidden for either the husband or the wife to spread any of the secrets of their bedroom to anyone outside. The following two hadîth are about this:
First:
“Verily among the worst people before ALLÂH on the Day of Judgement is a man who approaches his wife sexually and she responds and then he spreads her secrets.” [Muslim, Ibn Abi Shaiba, Ahmad and others].
Second: “On the authority of Asmâ bint Yazid who narrated “that she was once in the presence of the Prophet and there were both men and women sitting. The Prophet then said:
“Perhaps a man might discuss what he does with his wife, or perhaps a woman might inform someone what she did with her husband?” The people were silent. Then I said: “O, Yes! O Messenger of Allâh verily both the women and men do that.” Then the Prophet said: “Do not do that. It is like a male shaitân who meets a female shaitân along the way, and has sex with her while the people look on!” [Ahmad: Hasan or Sahîh due to supports]. *_May ALLAH keep guiding us all and protect us from any satanic influences_*. Aameen.
