Can you explain me about women Asma, Asma is women who married with one sahaba & two khalifa (Abobakar & Ali)

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger.

Al-Haafith ibn Hajar wrote the biography of this female companion in his book Al-Isaabah, and we will quote part of it with slight modifications. He wrote,

“Her name is Asmaa’ bint ‘Umays ibn Ma‘d from the tribe of Khath‘am. She was the maternal sister of Maymoonah bint Al-Haarith the wife of the Prophet, sallallaahu ‘alayhi wa sallam, and sister to a group of female Companions. She was one of the early female Companions who migrated to Abyssinia as she migrated there with her husband Ja‘far ibn Abi Taalib . She gave birth to his children there. When Ja‘far was killed, Abu Bakr married her, and she gave birth to his son Muhammad. Later she got married to ‘Ali and it is said that she gave birth to his son ‘Awn.”

Ibn Hajar did not mention the date of her death, but in “Taqreeb At-Tahtheeb”, he said that she died after ‘Ali and he did not mention the year in which she died. We did not find any scholar mentioning the year of her death.

Allaah Knows best.
