The Prophet’s first wife and an early supporter of the revelation.
Life in Makkah
Khadijah bint Khuwaylid was the first wife of Prophet Muhammad. Biographical tradition describes her commercial activity in Makkah and her confidence in his honesty. Their marriage preceded the beginning of the prophetic mission. She was the mother of Lady Fatimah and occupied a central place in the Prophet’s family life.
Support during the first revelation
Accounts of the first revelation describe Khadijah reassuring the Prophet and helping him seek an explanation from Waraqah ibn Nawfal. She supported him during the difficulties of the Makkan period. Her death occurred before the Hijrah; detailed dates and some family reports differ among sources. The TDV article identifies the underlying biographical and hadith references. Read those references alongside the Seerah rather than treating every later retelling as equally established.
