Sunan Abi Dawud, 2195

Narrated Abdullah ibn Abbas: Divorced women shall wait concerning themselves for three monthly periods. Nor is it lawful for them to hide what Allah hath created in their wombs. This means that if a man divorced his wife he had the right to take her back in marriage though he had divorced her by three pronouncements. This was then repealed (by a Qur'anic verse). Divorce is only permissible twice

Rapporté par Abdullah ibn Abbas رضي الله عنه : Les femmes divorcées doivent attendre trois cycles menstruels. Il ne leur est pas permis de cacher ce qu’Allah a créé dans leur ventre. Cela signifie que si un homme divorçait de sa femme, il avait le droit de la reprendre même s’il avait prononcé trois divorces. Cela a ensuite été abrogé (par un verset du Coran). Le divorce n’est permis que deux fois
