Khadijah (خديجة) was the first wife of the Prophet Muhammad and the first convert to Islam. A wealthy businesswoman of Mecca, she supported the Prophet through his earliest revelations and is revered as the "Mother of Believers."
Khadijah is widely used in the Muslim world. Khadijah Williams is the contemporary American activist.
Khadijah does not currently appear in the US Social Security Administration's top 1,000 girls' names, so we don't publish a US rank or birth count for it. That says nothing about the name's standing elsewhere in the world — only that it sits outside the ranked US data we rely on.
In Pythagorean numerology the letters of Khadijah reduce to 7, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
