[Test]
If someone bring a gold bar to you, will you immediately accepted the gold bar and pay them a lump sum of money or would you test the authenticity of the gold bar 1st...???
Most probably your answer is to test the authenticity of the gold bar 1st right?
If so, why when someone told you this is god or that is god we accept without putting the 'god' to test?
It is worst still if a Muslim belief in something pertaining to Islam without questioning where did the person get it from and what is the evidence...
