It is narrated from Sayyiduna Ibn Mas'ud (may Allah be pleased with him) that the Prophet (peace and blessings of Allah be upon him) said: "No woman should touch her naked body with 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. When you are three people, then two of you should not whisper to each other leaving the third one out, because this will cause the third one grief. And whoever seizes the wealth of a Muslim by swearing a false oath, he will meet Allah in such a state that Allah will be angry with him." Upon hearing this, Sayyiduna Ash'ath (may Allah be pleased with him) said that this command was revealed regarding my incident, the details of which are that there was a well shared between me and a Jew, and we brought our case before the Prophet (peace and blessings of Allah be upon him).
