Zaheen is an Arabic name for boys and girls that means "intelligent", "clever", "perceptive". It is not from the Quran but Muslim can use it since it has a good meaning. It is pronounced [(Z)oom + r(U)n] + [(HEE)d + (N)ew]. It is written as ذهين in Arabic.
Zaheen also has a girl-only version, Zaheena, which has the same meaning and is pronounced [(Z)oom + r(U)n] + [(HEE)d] + [(NU)mber].
