Crypto-Muslims deceived each other as well as their Christian overlords.

Evidence

What is at issue here is not the systematic deceit (taqiyya) that was forced on the Muslims of Spain by the forced conversion, but the way that the Young Man himself and some of the individuals in the circles he describes (Nuzaya Calder´an, for example) set out to deceive their Morisco readers and sometimes to deceive one other. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 832

Categorization

• DEFINE: Distinguishes taqiyya (deceit forced from without) from internal, voluntary deception among crypto-Muslims themselves.
