The Coalition - 33:50
We have made lawful for you, O Prophet, your wives whom you have given their Mahr and those under your hand whom Allah has bestowed upon you, and the daughters of your uncles and the daughters of your aunts and the daughters of your uncles and the daughters of your aunts who have migrated with you. Moreover, if the Prophet wishes, he may marry one who has given herself to the Prophet only, and not to the believers. And We have made known to them about their wives and those who are under their hands, so that you may not be in a difficult situation, and Allah is Forgiving, Merciful.
Notified responsibilities towards spouses:
The Women/4:34
Men watch over women. For Allah has given each of them different abilities and qualities. Indeed, men are responsible for the maintenance of the household. The righteous women submit (to God´s law) and protect (their honor and chastity) which God has commanded them to protect, even if they are alone. Admonish those women whose chastity you are concerned about, separate your beds, and finally remove them. If they obey you, do not seek a way against them. Allah is the Great, the Exalted.
The Women/4:129
You cannot treat women equally, no matter how much you want to. So do not incline wholly to one and leave the other in suspense. If you correct this situation and become virtuous, Allah is Forgiving, Merciful.
