She was regarded as one of the female Companions distinguished for their legal understanding.

Al-Waqidi said: ʿUmar ibn ʿUthman narrated to us, from ʿAbd al-Malik ibn ʿUbayd, from Saʿid ibn Yarbuʿ, from ʿUmar ibn Abi Salamah, who said:
“The Messenger of Allah ﷺ dispatched my father to Abu Qatan in Muharram of the year 4 AH. He was away for twenty-nine nights, then he returned in Safar, and the wound he had sustained on the Day of Uhud had reopened; he died from it on the eighth of Jumada al-Akhirah. My mother’s waiting period ended in Shawwal, and the Messenger of Allah ﷺ married her.

He went on to say: She passed away in Dhu al-Qaʿdah of 59 AH (1).”

Ibn Saʿd said: Ahmad ibn Ishaq al-Hadrami informed us; ʿAbd al-Wahid ibn Ziyad narrated to us; ʿAsim al-Aḥwal narrated to us, from Ziyad ibn Abi Maryam:
Umm Salamah said to Abu Salamah, “I have heard that if a woman’s husband—being of the people of Paradise—dies and she does not remarry, Allah will reunite them in Paradise. So come (2), let us pledge that you will not marry after me, and I will not marry after you.”

He asked, “Will you obey me?”
She replied, “Yes.”
He said, “Then if I die, marry. O Allah, provide Umm Salamah after me with a man better than I, one who will neither grieve her (3) nor harm her.”

When he died, I said, “Who could possibly be better than Abu Salamah?” Not long afterward, the Messenger of Allah ﷺ came, stood at the door, and spoke of the proposal through her nephew—or her son.

She said, “Shall I turn down the Messenger of Allah, or put myself ahead of him because of my children?”

The next day he came and made the formal proposal (4).
