Rehema is the Swahili word for "mercy" or "compassion" — from the Arabic raḥmah, sharing the root with Rahman (Most Merciful), one of the 99 Names of Allah.
Rehema is widely used in East Africa.
Rehema 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 Rehema reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
