taqiyya

ossia: la santa dissimulazione, l'autorizzazione che il musulmano ha di mentire agli infedeli

vedete il link nel titolo, suggerisco una lettura completa, ma intanto eccone alcuni estratti:

"Taqiyya has been used by Muslims since the 7th century to confuse and split 'the enemy’. A favored tactic was ‘deceptive triangulation’; to persuade the enemy that jihad was not aimed at them but at another enemy. Another tactic was to deny that there was jihad at all. The fate for such faulty assessments by the target was death. "

"Rather than admitting that a proposition concerning a state of affairs can be partly true, an Islamic spokesman will deny a claim or proposition in absolute terms. For example, “It is impossible to be a Muslim and a terrorist’ , which is false and ‘Islam forbids suicide’, which is true, but irrelevant as suicide or martyrdom attacks are not forbidden in the Koran."
