Nusrat is from the Arabic nuṣrah (نصرة — help, victory, divine support). Nusrat Jahan Ruhi (born 1990) is a Bengali cinema actress and Indian politician — widely considered one of the leading Bengali contemporary actresses of the 2010s and 2020s.
Nusrat 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 Nusrat reduce to 3, The Communicator. This is a traditional interpretive system, not a factual claim about the name.
