Siddiq
Siddiq (Arabic: صِدّيق, romanized: ṣiddīq) is an Arabic term denoting "the truthful one" or "verifier of truth," derived from the root ṣ-d-q, which pertains to sincerity, righteousness, and affirmation of veracity.[1][2] In Islamic tradition, it is employed as an honorific title for individuals exemplifying unwavering truthfulness and loyalty, most notably Abu Bakr ibn Abi Quhafa, the closest companion of the Prophet Muhammad and the first Rashidun caliph, who received the epithet Abū Bakr al-Ṣiddīq for his immediate acceptance of the Prophet's account of the Isra and Mi'raj without hesitation.[3][4] The term appears in the Quran in the plural form siddiqin to describe the righteous alongside prophets, martyrs, and the pious, underscoring its connotation of profound fidelity to divine truth.[2]
