So what if Muslims are allowed to save their lives by hiding their beliefs, so what is wrong with disciples of Jesus doing the same. It only shows saving lives is more important. If one continues to live he can always return to struggle another day! BTW the word Taqiyya is not found n the Quran.
Essentially, the Koran suggests that a person who faces religious persecution can withhold the identity of their faith in order to avoid bodily harm or death. The concept was particularly embraced by Shiites, who took steps to hide their religious beliefs from the majority Sunnis. (Indeed, part of the reason for Sunni distrust of Shiites is because Sunnis regard taqiyya as part of Shiite practice.)
But some Sunnis also practiced taqiyya, particularly the Moriscos, Muslims who were forced to convert to Catholicism in Spain during the 1500s.
The concept is also not unknown to other religions. Jews in Spain during the Inquisition also pretended to convert to Catholicism.
