Egyptian grand mufti says Muslims can convert to other religions

Re: Egyptian grand mufti says Muslims can convert to other religions

They use the example of Moses saying to the isrealites: uqtiloo anfusikum... kill your nafs/ego... and they translate it as "kill yourselves (the wrongdoers)", which of course does not make sense since it is based on a biblical insertion... If God needed to say "the wrongdoers", it would have been expressed explicitly (God makes mistakes?)
