Sâdıka
While the name Sâdıka itself does not appear as a personal name in the Quran, the root s-d-q (truth) appears frequently, and the masculine form Sadiq is mentioned in various contexts.
Sâdık is the masculine form meaning 'truthful man,' while Sâdıka is the feminine form meaning 'truthful woman,' both derived from the same Arabic root s-d-q.
Sâdıka was never common but appears in historical records as a distinguished name among Ottoman scholarly and noble families, particularly in the 17th and 18th centuries.
Arab countries typically use Sadiqa or Siddiqa, while Sâdıka with the circumflex is specific to Ottoman Turkish orthography and rare in modern usage.
The name represents truthfulness (sidq), sincerity in faith and speech, faithfulness in relationships, and moral integrity.
