Sabah is from the Arabic صباح (Ṣabāḥ — morning, dawn, daybreak). Sabah is one of the Arabic feminine + unisex names — central to traditional Muslim heritage. Arabic feminine name reflecting Arab musical heritage.
Sabah 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 Sabah reduce to 4, The Builder. This is a traditional interpretive system, not a factual claim about the name.
