Anyone Might Become a Ṣiddīq
Imām Ibn Taimiyyah, may Allāh have mercy on him, said:
All sins are conceivable for the ṣiddiqūn,¹ as agreed upon by the imāms; a man might be a disbeliever, repent after that from disbelief, and become a ṣiddīq; he might be a sinful transgressor or disobedient sinner and then repent of his transgressions and disobedience and become a ṣiddīq.
