The Prohibition - 66:5 If he divorces you, perhaps his Lord will give him in your place wives better than you, active widows and young wives, who are submissive, believing, devoted, devoted, devoted, worshipful
It is forbidden to marry the wives of prophets when they die or divorce their wives:
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.
The Coalition/33:6 The Prophet is closer to the believers than they are to themselves, and his wives are their mothers. According to the Book of Allah, the believers should give priority to those who are related to them among the emigrants. Except that you do good to your friends. These things are codified in this Book.
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.
