mmm that is one of the few good points I have heard pm say..

 

it is very important not to judge muslims on actions which are unclear in the Quran or the Sunnah.

 

That does not mean that a person cannot be defined by their actions as a non muslim but not by everyday muslims who lack knowledge.  

because it is something we must tread very carefully. Even amongst scholars (who avoid this to no end) can talk about the characteristics that take a person outside the fold of islam.. such as doing magic or mocking the religion.. however it is very difficult to suggest any individual person or group has become non muslim. Because the prophet said.. anyone who declares a person a non muslim and he is truly not a kaafir then he becomes one himself.

 

So it is very important to have a clear knowledge within Islam before calling another person or even thinking they are a non muslim. And even amongst the scholars it must be upon clear evidence and the person must have been explained his actions very clearly as well.  And we do not know what is in a persons heart.

On the day of judgement a person who was a muslim his whole life will all of a sudden turn non muslim before he died and enter hell fire. And a person who was an atheist will become a muslim..
