Taqiyya

In Islam, Taqiyya, and also kitman, is a doctrine of pious fraud or religious dissimulation, derived from Suras such as III.28, whereby Muslims may under certain circumstances openly deceive infidels by feigning friendship or goodwill provided their heart remains true to Islam. Historian Al-Tabari [died 923 C.E] wrote on Sura XVI.108, "If anyone is compelled and professes unbelief with his tongue, while his heart contradicts him, in order to escape his enemies, no blame falls on him, because God takes his servants as their hearts believe." -- Adapted from The Encyclopaedia of Islam, 2 Edn., and The Al-Qaeda Reader, ed.
