The Cow - 2:187
It has been made lawful for you to have sexual intercourse with your women on the nights of fasting. They are your coverings and you are their coverings. Allah knew that you were deceiving yourselves, so He accepted your repentance and forgave you. Now you may have sexual intercourse with them as Allah has determined for you. Eat and drink until you can distinguish between the white and black threads of dawn. Then complete the fast until the night. Do not have sexual intercourse with them while they are confined in the mosques. These are the limits set by Allah; do not transgress them. This is how Allah reveals His verses to the people for their protection.
Whoever transgresses the laws of Allah:
The Cow/2:229
Divorce is twice. Divorced women should either be kept in kindness or left in kindness. It is not lawful for you to take back what you have given them, except if the spouses fear that they may not observe the limits of Allah. If you fear that you may not observe the limits of Allah, then they will not be guilty of sin for what she has willingly given back. These are the limits of Allah; do not transgress them. Whoever transgresses the limits of Allah, they are the wrongdoers.
The Women/4:14
Whoever disobeys Allah and His messenger and transgresses His laws, He will admit him into a Fire in which he will abide forever. For him is a humiliating torment.
Divorce/65:1
O Prophet, when you divorce women, observe the term of divorce and calculate it well. Listen to Allah, your Lord. And do not drive them out of their homes, nor should they drive them out (do not force them to do so by ill-treatment). Except if they commit proven adultery. This is the law of Allah. Whoever transgresses Allah´s law has wronged himself. You do not know, but perhaps Allah will bring about something (positive) after that.
