ﷺ
Sayyidatuna Khadija (may Allah be pleased with her) was a wealthy and very respectable woman of Makkah, belonging to Banu Asad. The people of Makkah would call her by the title 'Taahirah' — the chaste one — due to her chastity. She was 40 years old at the time of marriage. She remained in the servitude of the Holy Prophet (peace and blessings be upon him) for almost 25 years. He (peace and blessings be upon him) did not marry any other woman during her life.
