Sunan Abi Dawud, 309

Rapporté par Ikrimah : Umm Habibah avait des saignements prolongés et son mari avait des rapports avec elle. Abu Dawud a dit : Yahya b. Ma'in a jugé Mu'alla (un rapporteur de ce hadith) digne de confiance. Mais Ahmad b. Hanbal ne rapportait pas de traditions de lui car il donnait son opinion personnelle

Ikrimah said:Umm Habibah had a prolonged flow of blood ; her husband used to cohabit with her. Abu Dawud said: Yahya b. Ma'in has pronounced Mu'alla (a narrator of this tradition) as trustworthy. But Ahmad b. Hanbal would not report (traditions) from him because he exercised personal opinion
