And remember, she's 40, this would be her third marriage, and he is 25, and he accepts the proposal. Now, this is significant, because as we'll see in this video and the next, Khadijah is the first one to follow Muhammad or believe in Muhammad's revelations. So he continues to work with his wife, arguably work for his wife, and then in 610, he's now 40 years old, he is praying in a cave on the outskirts of Mecca, and while he's praying, he is purported to get his first revelation from God, according to Islamic traditions. And that first revelation, and this is the mountain where it is purported to happen, the mountain of light, Jabal al-Nur, this is the cave, Cave Hira. The first revelation is, proclaim in the name of thy Lord and Cherisher, who created man out of a clot of congealed blood. Proclaim, and thy Lord is most bountiful, who taught by the pen, taught man that which he knew not. And so Muhammad, according to Islamic accounts, he's kind of very concerned by this.
