Sidq - Truthfulness
The fundamental virtue of truthfulness in word, deed, and intention that defines good character.
Sidq (الصدق) is truthfulness in all its forms—truthful speech, truthful action, and truthful intention. The Prophet (PBUH) said: 'Truthfulness leads to righteousness, and righteousness leads to Paradise. A person keeps speaking truth until he is recorded as a truthful one (siddiq).' Conversely, lying leads to wickedness and Hell. Truthfulness requires courage, as truth may sometimes be difficult. Even in difficult situations, Islam permits only ambiguous speech, not lying. Building a reputation for truthfulness creates trust that benefits all relationships and transactions.
Truthfulness leads to righteousness, and righteousness leads to Paradise.
Abu Bakr as-Siddiq earned his title 'the Truthful One' because he immediately believed the Prophet about the miraculous night journey when others doubted.

- What Islam says about what to say and what to leave unsaid
Sidq covers truthful speech, truthful action and truthful intention together, and the hadith traces a chain from truthfulness to righteousness to Paradise. The restriction worth noticing: when truth is dangerous, Islam permits ambiguous speech but still not a lie.
