Dicle
Dicle is used by Muslim families in Kurdish and Turkish regions, but it is a toponymic name (derived from the Tigris River) rather than a name rooted in Quranic or Prophetic tradition.
Dicle is the local Kurdish/Turkish name for the Tigris River (Dijla in Arabic). The personal-name usage evokes the river and regional heritage of Mesopotamia.
No specific verse in the Quran names the Tigris as 'Dijla' or 'Dicle'; therefore there is no direct Quranic citation for the proper name Dicle.
Dicle is uncommon internationally but used regionally among Kurds and Turks; its popularity is low outside Anatolia and Kurdistan.
Yes — common variants in transliteration include Dijla and Dijlah (closer to the Arabic form دجلة). In Turkish orthography it appears as Dicle.
