Ummu Kulthum bint Abu-Bakr, the first caliph of the prophet (peace be upon him). She was the third daughter of the caliph (may Allah be pleased with him). Her mother was Habeebah Bint Kharijah, the fourth wife of the caliph.
Abu-Bakr (may Allah be pleased with him) told Aisha before his death that Habiba was pregnant and that he suspected it to be a girl. Ummu Kulthum was born in Medina shortly after her father's death. She was not among the companions of the prophet, because she was born after the prophet's death. So she was a successor of the prophets' companions.
Umm Kulthum married Talha ibn Ubayd-Allah, who was among the ten blessed with the glad tidings of Paradise by the Messenger of Allah (peace and blessings of Allah be to him). She gave birth to Zakariyyah, Yusuf (who died in infancy) and Aisha. Talha was killed at the Battle of the Camel in 656.
Talhah (may Allah be pleased with him) was an astute and successful merchant who travelled widely to the north and south of the Arabian Peninsula. It is said that after one of his trips to Hadramawt, he had profits amounting to some seven hundred thousand dirhams. His nights would be anxious and worried on account of this vast wealth. On one such night, his wife, Umm Kulthum said to him: "What's wrong with you, O father of Muhammad? Perhaps I have done something to hurt you?" "No," replied Talhah. "You are a wonderful wife for a Muslim man. But I have been thinking since last night: How can a man think of his Lord and Sustainer when he goes to sleep with this wealth in his house?"
"Why should it bother you so much،" remarked Umm Kulthum. "What about all the needy ones in your community and all your friends? When you get up in the morning share it out among them." "God bless you. You are really marvellous, the daughter of a marvellous man," said Talhah to his wife. In the morning, Talhah gathered up the money in bags and distributed it between the poor Muhaajireen and Ansaar.
Thereafter she married Abdulrahman ibn Abdullah al-Makhzumi. She bore him Ibrahim al-Ahwal, Musa, Umm Humayd and Umm Uthman.
Umm Kulthum was a successor. She narrated hadith from Aisha, of which some were collected by al-Bukhari, Muslim, al-Nasa'i and Ibn Majah.
May Allah be pleased with her, for she was a woman of intelligence and generosity.
