In one narration, also from Sayyiduna Ubadah bin al-Samit (may Allah be pleased with him), these words are reported. He narrates: One of my forefathers gave his wife a thousand divorces. His sons came to the Prophet (peace and blessings be upon him) and said: "Our father has given our mother a thousand divorces; is there any way out?" The Prophet (peace and blessings be upon him) said: "Your father did not fear Allah Almighty, otherwise Allah Almighty would have made a way out for him. On the basis of three divorces that woman has become separated from this man, and this is against the Sunnah; and nine hundred and ninety-seven divorces are a sin upon this man's neck." Al-Tabarani recorded all of these narrations. Its chain contains a narrator, Ubaydullah bin al-Walid al-Wassafi al-Ijli, who is da'if (weak).
