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

And when you have divorced women and they have fulfilled the term of their prescribed period, either take them back on reasonable basis or set them free on reasonable basis. But do not take them back to hurt them, and whoever does that, then he has wronged himself. And treat not the Verses (Laws) of Allâh as a jest, but remember Allâh’s Favours on you (i.e. Islâm), and that which He has sent down to you of the Book (i.e. the Qur’ân) and Al-Hikmah (the Prophet’s Sunnah - legal ways - Islâmic jurisprudence.) whereby He instructs you. And fear Allâh, and know that Allâh is All-Aware of everything.
