FYI:
Taqiyya
From Wikipedia, the free encyclopedia.
In Shi'a Islamic tradition, Taqiyya (التقية) is the dissimulation of one’s religious beliefs when one fears for one's life, the lives of one's family members, or for the preservation of the faith. It is most often used in times of persecution or danger. Some Sunnis assert that Taqiyya is an act of hypocrisy that serves to conceal the truth. According to them, Taqiyya constitutes a lack of faith and trust in God because the person who conceals his beliefs to spare himself from danger is fearful of humans, when he should be fearful of God only.
The practice was a method of self-preservation for the Shi'as who historically were the minority and persecuted by Sunni Muslims. Sunnis would sometimes force Shi'as to curse the House of Ali - believing that no devout Shi'a could commit such an act. As a result of this persecution, the idea of Taqiyya emerged. In other words, if a Shi'a Muslim's life is in danger, he may lie as long as he holds his faith true in his heart.
Shi'as justify the practice using the following verse from the Qur'an:
Any one who, after accepting faith in Allah, utters Unbelief,- except under compulsion, his heart remaining firm in Faith - but such as open their breast to Unbelief, on them is Wrath from Allah, and theirs will be a dreadful Penalty. Sura 16:106
And the following
[Shakir 3:28] Let not the believers take the unbelievers for friends (awliyaa) rather than believers; and whoever does this, he shall have nothing of (the guardianship of) Allah, but you should guard (tattaqoo) yourselves against them, guarding carefully (tuqatan); and Allah makes you cautious of (retribution from) Himself; and to Allah is the eventual coming.
According to Shi'a interpretation of these verses, 3:28 is telling that believers should not take unbelievers as Walis rather the believers, those who do it will lose the wilayat (5:55) of God, that is unless they are using taqiya/protecting them self, and doing so with caution. And God knows what is in your heart, so fear his wrath, for nobody escapes God.
