At-Talaq · 65:2

2. So when they draw nearer to the end of their waiting periods, take them back if you long to do so, while maintaining the best of conduct, or do not take them back until their waiting periods finish and they gain control over their own affairs, after fulfilling for them their rights. And if you intend to either take them back or separate from them, make two honest people from among you witness it to dispel any dispute in future. O witnesses! Give testimony seeking the pleasure of Allah. These laws are mentioned to remind those that bring faith in Allah and in the Day of Judgement, because it is them who truly benefit from reminders and advice. And whoever is mindful of Allah by fulfilling His commands and refraining from the things He has not allowed, Allah will create an exit for him from every difficulty and worry.
