Al-Baqarah 2:231 واذا طلقتم النساء فبلغن اجلهن فامسكوهن بمعروف او سرحوهن بمعروف ولا تمسكوهن ضرارا لتعتدوا ومن يفعل ذالك فقد ظلم نفسه ولا تتخذوا ايات الله هزوا واذكروا نعمت الله عليكم وما انزل عليكم من الكتاب والحكمة يعظكم به واتقوا الله واعلموا ان الله بكل شيء عليم ٢٣١

When ye divorce women, and they fulfil the term of their ('Iddat), either take them back on equitable terms or set them free on equitable terms; but do not take them back to injure them, (or) to take undue advantage; if any one does that; He wrongs his own soul. Do not treat Allah's Signs as a jest, but solemnly rehearse Allah's favours on you, and the fact that He sent down to you the Book and Wisdom, for your instruction. And fear Allah, and know that Allah is well acquainted with all things.
