Hadith 10:877
Abu Bakr narrated to us, he said: Abda narrated to us, from Ibn Abi Arubah, from Qatadah, from al-Hasan, who said: If a man swears an oath (of abstention) regarding his wife, and he bears witness that he has returned (to her), then that is for him.
حدثنا أبو بكر قال نا عبدة عن بن أبي عروبة عن قتادة عن الحسن قال إذا آلى الرجل من أمرأته فأشهد أنه قد فاء فذلك له
