Tasneem (تسنيم) is the Quranic Arabic word for the highest fountain in paradise — mentioned in Sura 83 of the Quran. The waters of Tasneem are reserved for the most pious.
Tasneem is widely used in the Muslim world.
Tasneem 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 Tasneem reduce to 5, The Seeker. This is a traditional interpretive system, not a factual claim about the name.
