  Translation

230. And if he has divorced her (the third time), then she is not lawful unto him thereafter until she has married another husband. Then, if the other husband divorces her, it is no sin on both of them that they reunite, provided they feel that they can keep the limits ordained by Allâh. These are the limits of Allâh, which He makes plain for the people who have knowledge.
