Sunan Abi Dawud, 309

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

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
