The Coalition - 33:32 O wives of the Messenger, you are not like any other woman. If you are virtuous, do not speak coquettishly, lest someone whose heart is diseased turn to you. Speak in a beautiful and normal way.
When the wives of the Prophet were talking:
The Coalition/33:53 O you who believe, do not enter the house of the Messenger until you are called to eat. Nor wait for such a call. You may enter when you are called. After you have eaten, leave and disperse. Do not engage in hadiths (sayings). This grieved the Prophet, but he was ashamed to inform you. Allah is not ashamed to declare the truth. When you ask something of his wives, ask them behind a veil. This is purer for your hearts and their hearts. You must not grieve the Messenger of Allah and you must not marry his wives after him, for that is a great sin in the sight of Allah.
