She was Khadijah bint (daughter of) Khuwaylid ibn (son of) Asad ibn Abd-ul-Uzzaa ibn Qusayy. Khadijah was of the Quraysh. The lineage of the Prophet (pbuh) meets with her in the celebrated Qusay. Qusay was the great founder of Makkah and was the famous patriarch of the Quraysh.
When Khadijah heard of the Prophet’s wonderful moral conduct, she requested him to head her trading caravans. When he went on a business trip to Syria along with her trusted slave Maisarah, this trip proved extremely profitable. During the journey, Maisarah noticed wonderful qualities in the Prophet (pbuh), such as honesty, adherence to noble principles, agreeable dealings and business skills. The Prophet (pbuh) succeeded very well in his business mission. The profits were unusually high.
Khadijah was very wealthy and had a strong and independent will. She had repeatedly declined marriage propoals made by some of the most prominent men of the Quraysh. However, when the Prophet (pbuh) returned back home and Maisarah reported all that he had seen during the trip. Khadijah was deeply impressed by the Prophets fantastic character. She expressed her wish to marry him through her friend sah, and he agreed. His marriage to Khadijah took place about fifteen years before the beginning of the revelation. The Prophet (pbuh) as twenty-five and she was forty years old. Khadijah understood the Prophet (pbuh) and remained deeply devoted to him and morally supported him throughout her life.
When the Prophet (pbuh) married her, he was in the prime of his youth. The marriage proved to be one of affection and happiness. Khadijah is bore the Prophet (pbuh) all his children except Ibraaheem, whose mother was Maariyah. His sons from Khadijah were Al-Qaasim and Abdullah (also known at-Taahir and At-Tayyib), and his daughters from her were Zainab, Ruqayyah, Umm Kulthoom and Fatimah. All his sons died very young during his lifetime.
During his solitary retreat in the Cave of Hira, the Prophet (pbuh) used to be quite alone most of the time, but Khadijah would visit him from time to time and would also bring along his little daughters.
The appearance of Angel Jibreel at Hira and consequently, the first revelation of the Quran took place during the month of Ramadan. The Prophet (pbuh) was at that time forty years old. When he returned home from the Cave of Hira, his heart was trembling. He told Khadijah, “Wrap me up, wrap me up.” Then he told her what had happened. It was Khadijah who stood by him and comforted him. She said, “Allah will never humiliate you. You fulfill the duties of kinship; you support the weak; you help the poor and the needy; you honour your guests and endure hardships in the path of truthfulness.” She then took him to her cousin Waraqah ibn Nawfal, who became before lslam a Christian and had knowledge of the previous divine books. waraqah told him that the angel who had come to him was the same angel whom Allah sent to Prophet Musa. He also told him that his people would drive him out because every prophet who came with the same massage was treated with hostility from his people.
Although the Prophet (pbuh) was fifteen years younger than Khadijah, he never thought of marrying another woman as long as she lived
Allah’s Messenger (pbuh) said of her, “The best of the women of her time was Maryam, daughter of lmran, and the best of the women of her time was Khadijah, daughter of Khuwaylid.”
Allah’s Messenger (pbuh) loved her very much. He often praised her. On one occasion, when Khadijah was still alive, Jibreel came to the Prophet (pbuh) and said, “…Give her greetings of peace from her Lord and from me, and give her the good news of a palace of jewels in Paradise, where there will be neither noise nor any tiredness.”
The Prophet (pbuh) often mentioned Khadijah’s outstanding merits. He used to say, “She believed in me when no one else did; she accepted Islam when people rejected me and she helped and comforted me when there was no one else to lend me a helping hand.”
She died about three years before the hijrah. This incident affected the Prophet (pbuh) so much that his companions always referred to the year in which she died as the year of grief.
