Hadeel (هديل) is the Arabic word for "the cooing of a dove." The sound evokes peace, family, and morning.
Hadeel is widely used in the Arab world.
Hadeel 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 Hadeel reduce to 8, The Visionary. This is a traditional interpretive system, not a factual claim about the name.
