Taqiyya (al-Taqiyya, also spelled Al-Takeyya) is a concept in Shia Islam which encourages "disguising one's beliefs, intentions, convictions, ideas, feelings, opinions or strategies," especially when failing to do so may put the believer at risk. It is authorized under the Qur'an and Sunna.[Citation Needed]
Taqiyya allows a Shia Muslim even "to deny or denounce his faith if, in so doing, he protects or furthers the interests of Islam, so long as he remains faithful to Islam in his heart." Taqiyya further permits "lying under oath in testimony before a court, deceiving by making distorted statements to the media such as the claim that Islam is a 'religion of peace.'" Most Muslim scholars teach that this should only be done when necessary.
Islamic Review states, "The Arabic word, "Takeyya", means "to prevent," or guard against. The principle of Al Takeyya conveys the understanding that Muslims are permitted to lie as a preventive measure against anticipated harm to one's self or fellow Muslims. This principle gives Muslims the liberty to lie under certain circumstances. They can even deny the faith, if they do not mean it in their hearts. Al-Takeyya is based on the following Quranic verse: Let not the believers Take for friends or helpers Unbelievers rather than believers: if any do that, in nothing will there be help from Allah: except by way of precaution (prevention), that ye may Guard yourselves from them (prevent them from harming you.) But Allah cautions you (To remember) Himself; for the final goal is to Allah. Surah 3: 28"

- Islamic Review, Lying in Islam, by Abdullah Al Araby  The mission statement for Islamic Review, a Christian organization, states, "Muslim activists, in their attempt to spread their religion in the West, have been deliberately hiding a certain side of their religion. They carefully avoid, obscure and omit any negative teachings of Islam in order to lure converts. Our mission is to expose these teachings that are withheld from seekers in order to help people gain a more realistic insight of what it is like to live under Islam."
