"Taqīyah is the precautionary dissimulation of religious belief and practice in the face of persecution. Muslims recognize the personal duty of affirming right and forbidding wrong, but when confronted by an overwhelming injustice that threatens the well-being of an individual, this obligation can be fulfilled secretly in the heart rather than overtly."
