2:229Divorce is allowed twice. Then, either honorable retention, or setting free kindly. It is not lawful for you to take back anything you have given them, unless they fear that they cannot maintain God's limits. If you fear that they cannot maintain God’s limits, then there is no blame on them if she sacrifices something for her release. These are God’s limits, so do not transgress them. Those who transgress God’s limits are the unjust.

2:230If he divorces her, she shall not be lawful for him again until she has married another husband. If the latter divorces her, then there is no blame on them for reuniting, provided they think they can maintain God's limits. These are God’s limits; He makes them clear to people who know.

2:234As for those among you who die and leave widows behind, their widows shall wait by themselves for four months and ten days. When they have reached their term, there is no blame on you regarding what they might honorably do with themselves. God is fully acquainted with what you do.

2:240Those of you who die and leave wives behind—a will shall provide their wives with support for a year, provided they do not leave. If they leave, you are not to blame for what they do with themselves, provided it is reasonable. God is Mighty and Wise.

2:282O you who believe! When you incur debt among yourselves for a certain period of time, write it down. And have a scribe write in your presence, in all fairness. And let no scribe refuse to write, as God has taught him. So let him write, and let the debtor dictate. And let him fear God, his Lord, and diminish nothing from it. But if the debtor is mentally deficient, or weak, or unable to dictate, then let his guardian dictate with honesty. And call to witness two men from among you. If two men are not available, then one man and two women whose testimony is acceptable to all—if one of them fails to remember, the other would remind her. Witnesses must not refuse when called upon. And do not think it too trivial to write down, whether small or large, including the time of repayment. That is more equitable with God, and stronger as evidence, and more likely to prevent doubt—except in the case of a spot transaction between you—then there is no blame on you if you do not write it down. And let there be witnesses whenever you conclude a contract, and let no harm be done to either scribe or witness. If you do that, it is corruption on your part. And fear God. God teaches you. God is aware of everything.
