It is reported that ‘Ā`ishah – said, “Umm Ḥabībah called for me on her deathbed and said, ‘There used to occur between us the kinds of things that happen between co-wives (al-ḍarā`ir), so may Allāh forgive me and you those things.’ I said, ‘May Allāh forgive you all those things and release you from [all liability] for that.’ She replied, ‘You have made me happy, may Allāh make you happy.’ And she sent for Umm Salamah and said the same things to her.”
