if he divorces her she shall not be lawful to him after that until she has wed another spouse and then if he divorces her it shall be no offense for either of them to return to each other if they think that they can keep within the bounds of allah. those are the bounds of allah. he makes them plain to people who know.
فإن طلقها فلا تحل له من بعد حتى تنكح زوجا غيره فإن طلقها فلا جناح عليهما أن يتراجعا إن ظنا أن يقيما حدود الله وتلك حدود الله يبينها لقوم يعلمون
