And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they [i.e., all parties] agree among themselves on an acceptable basis. That is instructed to whoever of you believes in Allāh and the Last Day. That is better for you and purer, and Allāh knows and you know not.
