Siddiq (صدیق Arabic word meaning "truthful") is an Islamic term and is given as an Honorific title to certain individuals. The feminine gender for Siddiq is Siddiqah. The word is sometimes used as a title given to individuals by Muhammad, according to Islamic sources. Otherwise, it is used to denote that the person is totally trustworthy.
In Sufism, Siddiq is a rank that comes after prophet. It is generally given to a person who verified the claim of prophethood in its early stage. Sufis believe the following four ranks are free of time and space and therefore life and death becomes meaningless to them.
- Nabi – Prophet, someone who learned of the unseen from God directly
- Siddiq – Early day Muslim who learned the unseen from Muhammad
- Shaheed – Martyr, someone who gave their life for the will of God and has thus become beyond mortality.
- Salih – Righteous, someone who spends every bit of their life per the will of God and thus achieved the status of "Baqaa" through Fanaa. Also referred to as Wali.
These four ranks are mentioned in the Quran.
Shi'a Muslims use Siddiqah as a title for Muhammed's daughter Fatima. In Then I was Guided, the Shi'a author asks its Sunni audience how it is possible for both Abu Bakr and Fatimah to be "Siddiq", when contemplating their intense and deep conflicts, implying that logic demands one to be a liar, and arguing it can not be Muhammed's daughter . The Sunni view is that their conflict was a pure misunderstanding, not blemishing their trustworthiness.
