Khadīja bint Khuwaylid (Arabic: خديجة بنت خويلد) or Khadīja al-Kubra (Khadija the great)  (circa 555–619 CE) was the first wife of the Islamic prophet Muhammad. She was the daughter of Khuwaylid ibn Asad and Fatimah bint Za'idah and belonged to the clan of Banu Asad. She is important in Islam as Muhammad's first wife, and one of the "mothers of the believers". Three of her daughters would go on to marry Caliphs: Ruqayyah and Umm Kulthum married Uthman, and Fatima married Ali.
The first long-term relationship of Muḥammad ☮ was with Khadījah, a powerful older businesswoman who was also involved in humanitarian work. After the death of her first husband and before she knew Muḥammad ☮, Khadījah received many marriage offers from important Arabian men, yet she remained strongly independent.
When she heard about the growing reputation of Muḥammad ☮ as a man who is completely honest and someone can depend on, she reached out and hired him as a trader even though he was only 25 and had no significant business experience.
Muḥammad ☮ immediately excelled, and over time, Khadījah’s admiration for him gradually turned into a deeper affection. She initiated the marriage proposal herself.
When Muḥammad ☮ later experienced his first revelations, Khadījah became the first Muslim convert and for a time was the only one to give him full support when many prominent Meccans began to oppose him. Khadījah and Muḥammad ☮ remained life partners until the very end. Although it was permitted and common in his culture, Muḥammad ☮ took no other wives while she lived.
