English translation
[3653] (...) It was narrated from 'Abdullâh that he divorced one of his wives while she was menstruating, with a single divorce. The Messenger of Allâh ﷺ ordered him to take her back and keep her until she had become pure then menstruated again in his house. Then he should wait until she became pure again, then if he wished he could divorce her when she became pure, before having intercourse with her. That is the Iddah (prescribed periods) for which Allâh has enjoined the divorce of women. Ibn Rumh added in his report: "When 'Abdullâh was asked about that, he said to one of them: 'But if you have divorced your wife once or twice, the Messenger of Allâh ﷺ told me to do that (i.e., take her back), but if you have divorced her three times, then she becomes unlawful to you until she marries another husband; and you have disobeyed Allâh with regard to His commands about divorcing your wife." Muslim said: Al-Laith did well with his saying: "A single divorce (a narrator)."
