The existence of embassies, ambassadors and non-Muslims' investment authorities in Muslim countries is apostasy as it is deemed to be a kind of loyalty to non-Muslims; Allah says," Let not believers take disbelievers as allies rather than believers. And whoever [of you] does that has nothing with Allah, except when taking precaution against them in prudence. And Allah warns you of Himself and to Allah is the [final] destination". There are many verses forbidding loyalty to non-Muslims.
The existence of embassies, ambassadors and non-Muslims' investment authorities in Muslim countries has nothing to do with apostasy. Moreover, Prophet Mohamed –PBUH- sent messengers and ambassadors to other countries and met non-Muslims' delegations and ambassadors. How
can we consider Prophet Mohamed's action as apostasy?
Exalted are You, [O Allah]; this is a great slander!
