What does taqiya mean in Islam?
The word 'al-taqiya' literally means: "Concealing or disguising one's beliefs,
convictions, ideas, feelings, opinions, and/or strategies at a time of eminent
danger, whether now or later in time, to save oneself from physical and/or
mental injury."
A one-word translation would be 'dissimulation'.
dis·sim·u·la·tion
noun
concealment of one's thoughts, feelings, or character; pretense.
