Fatimah bint al-Khattab was the sister of the second Caliph Umar ibn al-Khattab along with Zayd ibn al-Khattab and one of the early women followers of the Islamic prophet, Muhammad. She was the youngest daughter of Khattab ibn Nufayl, who married her off with his nephew, hanif Sa'id ibn Zayd. Fatima along with her husband both converted to Islam together at the same time

Sa'īd eventually married Fatimah bint al-Khattab, and both became Muslims and hid their faith from Umar, the wife's brother, until the wife managed to contribute to Umar becoming a Muslim as well.
