It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: "When you are three people, then two of you should not whisper to each other excluding the third, for that will cause him grief. And no woman should touch her naked body to another woman so that she describes her physical features to her husband in such a way as if he is seeing her with his own eyes."
