Proof for being an atheist

[jenny1972]

did Prophet Muhammad himself select this " divinely appointed leader " ? if not how can you say that he is divinely appointed unless Muhammad chose him ? it is the choice and interpretation of humans who are not Prophets right just some religious person so how should they know what God wants ?

God tested infinite souls before bringing them into one of the worlds. Those who were of utmost sincerity to God were chosen, those who were exalted in intention, were chosen and trusted. 

He chosen the best of the best to seal his religion with.  It's up to God to chose who submitting to would be submitting to God himself, not the people. Even Moses asks God to appoint his brother Harun as a vizier with him, and helper, and doesn't chose on his own. Rather God must approve and choose.

Those who possess the authority from us are those who God vested his authority to who and who he manifests with clear proofs of their designation.

ok but what im asking is how do you humans know who exactly God has chosen to lead your religion ? what human being among you arrogantly claims to know who God has chosen and puts himself above Prophet Muhammed who did not even know ?

and you did not answer my above question :
did Prophet Muhammad himself say that this is an issue - that if not agreed upon - should be fought over? or did you Muslims decide that on your own ?
