The Cow - 2:226 Those who intend to divorce their wives should wait four months (for a sound decision). If they give up and reconcile, Allah is Forgiving, Merciful.
Divorce law in the Qur'an:
The Women/4:35 If you fear that the married couple may fall out, you should appoint an arbitrator from the man´s family and an arbitrator from the woman´s family. If they wish to reconcile, Allah will reconcile them. Allah is All-Knowing, All-Knower.

The Cow/2:226 Those who intend to divorce their wives should wait four months (for a sound decision). If they give up and reconcile, Allah is Forgiving, Merciful.
The Cow/2:227 If they are determined to divorce, Allah is All-Hearing and All-Knowing.
The Cow/2:228 The divorced women should wait three months for themselves (before marrying another). It is not fitting for them to conceal what Allah has created in their wombs if they believe in Allah and the Last Day. In that case (if they become pregnant) their husbands have more right to take them back if they wish to reconcile. Women have equal rights over men as men have rights over women, and men have a rank over them (in case of pregnancy). Allah is Mighty, Wise.
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 Cow/2:230 If he divorces her again (for the third time), she is not lawful for him after that unless she marries another. There is no harm in their returning to each other if they believe that they will observe the law of Allah. This is the law of Allah; We have made it clear for a people who know.
The Cow/2:231 When you divorce women, when they have finished their waiting period, either keep them with you in kindness or let them go in kindness. Do not keep them in such a way as to harm them in revenge. He who does that is wronging himself. Do not take the signs of Allah lightly. Think of Allah´s favors which He has bestowed upon you and of the Book and the wisdom which He has sent down to you for your admonition. Listen to Allah and know that Allah is All-Knowing.
The Cow/2:232 When the divorced women have finished their waiting period, do not prevent them from remarrying if they agree with their husbands in goodness. Those of you who believe in Allah and the Last Day take admonition from this. That is purer and healthier for you. Allah knows, even if you do not know.
The Cow/2:233 For those who wish to complete the period of breastfeeding, mothers should breastfeed their babies for two years. The mother´s need for food and clothing should be met by the father of the child in a good and proper manner. No one should be held responsible beyond his capacity. The mother should not be harmed because of her child, nor should the father be harmed because of his child. It is also the duty of the heir to realize this. If the parents want to wean after consultation and agreement, there is no sin on either of them. If you wish to have your children suckled by a wet nurse, you are not liable as long as you pay her properly. Listen to Allah, Allah is All-Seeing of what you do.
The Cow/2:234 The wives left behind by the men who die among you wait four months and ten (days). When they have fulfilled their term, there is no responsibility on you to do what is suitable for them. Allah is All-Knowing of what you do.
The Cow/2:235 There is no sin on you for informing them of your proposal of marriage, or for keeping this intention within you. Allah knows what you think about them. Do not meet them in secret except for the purpose of talking to them in a proper and virtuous manner. And do not attempt to marry them before their waiting period has expired. Know that Allah knows what is in you, so beware of Him. And know that Allah is Forgiving, Compassionate.
The Cow/2:236 It is permissible for you to divorce women before you have touched them or before they have paid their mahr. In that case, pay them. The rich should compensate them according to their means, and the poor should compensate them according to their means. This is the duty of the righteous.
The Cow/2:237 If you have divorced them after you have paid the bride price, but before you have touched them, you should give them half of the promised bride price. Unless the wife renounces her right or the husband wants to give the full amount. It is more virtuous for you to give it up. Remember the friendship between you. Allah is All-Seeing of what you do.
The Cow/2:240 Those of you who die and leave wives, let them make a will that their wives should be provided for for a year without leaving their homes. If they leave, you are not responsible for their doing what is proper for them. Allah is Mighty, Wise.
The Cow/2:241 Divorced women should also be given a suitable subsistence allowance. This is the duty of the righteous.

The Women/4:35 If you fear that the married couple may fall out, you should appoint an arbitrator from the man´s family and an arbitrator from the woman´s family. If they wish to reconcile, Allah will reconcile them. Allah is All-Knowing, All-Knower.

The Coalition/33:49 O you who believe, if you divorce believing women after you have married them and have not had sexual intercourse with them, they do not owe you a waiting period (before they marry another).

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.
Divorce/65:2 When they have fulfilled their term, keep them well, or separate them well. And take two just men from among you as witnesses. Bear witness for the sake of Allah. This is an admonition for those who believe in Allah and the Last Day. And whoever listens to Allah, He will create for him a way out.
Divorce/65:3 And gives him sustenance from where he does not expect it. Whoever trusts in Allah, He is sufficient for him. Allah is the One who fulfills His command. Allah has set a measure for everything.
Divorce/65:4 As for your women who have gone through menopause and have stopped menstruating, if you are in doubt, their waiting period is three months. And those who do not menstruate and are pregnant, their period ends when they give up their burdens. Whoever listens to Allah, He will make it easy for him.
Divorce/65:5 This is the Commandment of Allah which He has sent down to you. Whoever listens to Allah, He covers his evil deeds and increases his reward.
Divorce/65:6 Make those women sit where you sit, according to your strength. Do not disturb them to force them to leave. If they are pregnant, provide for them until they leave their burdens. If they nurse for you, pay them their wages. Establish a good relationship between you. If you have difficulty, another woman will nurse her.
Divorce/65:7 Let the wealthy give alimony in proportion to his wealth. And he who is of low income, let him give out of what Allah has given him. Allah does not burden anyone with more than what He has given him. Allah will bring ease after hardship.

The Women/4:19 Believers! It is not lawful for you to inherit the property of women against their wishes. Do not press them to take back from them what you have already given them. Except when they commit fornication. Get along well with them. If you dislike them, Allah has put much good in what you dislike.
The Women/4:20 If you want to leave your present wife and marry another wife, do not take anything back from her, even if you have given a large sum to the first one. Will you take it back by fraud and slander and sin?
The Women/4:21 How can you take it back when you were once each other´s closest friends and they took a firm promise from you?
