The request of Umm Habibah in her death bed

It is reported by Aisha (Radia Allahu anha):

"Umm Habibah called me in her death bed and said:
"Used to pass between us the kind of things that happens between the co-wives (al Dara-'ir), so May Allah forgive me and forgive you of these things."
I replied: "May Allah forgive you for all these things and release of (all) responsability for that".
She replied: "You have made me happy , may Allah make you happy."
And sent to call Umm Salamah and said the same things to her."
