divorce is twice. then either keep in an acceptable manner or release with good treatment. and it is not lawful for you to take anything of what you have given them unless both fear that they will not be able to keep the limits of allah. but if you fear that they will not keep the limits of allah then there is no blame upon either of them concerning that by which she ransoms herself. these are the limits of allah so do not transgress them. and whoever transgresses the limits of allah it is those who are the wrongdoers.
الطلاق مرتان فإمساك بمعروف أو تسريح بإحسان ولا يحل لكم أن تأخذوا مما آتيتموهن شيئا إلا أن يخافا ألا يقيما حدود الله فإن خفتم ألا يقيما حدود الله فلا جناح عليهما فيما افتدت به تلك حدود الله فلا تعتدوها ومن يتعد حدود الله فأولئك هم الظالمون
