- Origin: Arabic
- Meaning: “truthful; honest.”
Both names come from the Arabic root ṣ-d-q (ص د ق), which carries the sense of truth, sincerity, honesty, faithfulness.
- Siddīq (masculine) literally means “truthful, sincere, completely trustworthy.”
- Siddīqa (feminine) is the direct feminine form.
In Islamic tradition the title al-Ṣiddīq was famously given to Abu Bakr, the first caliph and closest companion of the Prophet Muhammad, highlighting his absolute honesty and faith.
The feminine al-Ṣiddīqa is used honorifically for Mary (Maryam) in the Qur’an (5:75) and also for Fāṭimah, the daughter of the Prophet, in later Islamic literature.
