Besides, the practice of concealing one's beliefs in dangerous circumstances originates in the Qur'an, which deems blameless those who disguise their beliefs in such cases. The practice of taqiyya in difficult circumstances is considered legitimate by Muslims of various sects. Sunni and Shia commentators alike observe that verse refers to the case of 'Ammar b. Yasir, who was forced to renounce his beliefs under physical duress and torture.
