Not true. If he is pretending to be “Christian” (Wright’s church is closer to the NOI & black liberation that true Christianity) for the purpose of advancing Islam in some way, this would be entirely acceptable as taqyyia.
Very true but if it by some no-name Muzzie without political ambitions who has converted out then the death penalty pretty much always applies.
100% of the Muzzie world thinks he is one their own. That definitely would preclude any issuance of a fatwa on the Impostor-In-Chief.
