Falak
Yes, the word Falak appears in Surah Al-Anbiya (21:33) describing the orbits of celestial bodies, making it a name with direct Quranic reference and spiritual significance.
Falak (فلك) means celestial sphere or orbit, while Falaq (فلق) means daybreak or splitting. Falak appears in Surah 21:33, whereas Falaq is the name of Surah 113 (Al-Falaq).
Falak is unisex. It is used for both boys and girls across Bengali, Persian, and Arabic-speaking communities, though slightly more common for girls in South Asia and boys in the Middle East.
In Persian poetry and literature, Falak represents the celestial vault, the wheel of fortune, and the vast heavens, often symbolizing destiny, cosmic order, and the grandeur of creation.
While rare as a given name historically, Falak appears in the pen names (takhallus) of several Persian and Urdu poets, such as Falak Shirazi, and is gaining modern usage as a distinctive first name.
