I don't believe that

This is one of the best explaination of why Allah allow the pain and suffering that I have seen:

A man went to a barbershop to have his hair cut and his beard trimmed.As the barber began the work,they began to have a good conversation.They talked about so many things and various subjects.When they eventually touched on the subject o Allah,

The barber said, 'I don't believe that'.'Why do you say that?' asked the customer.'Well you just have to go out in the street to realize that Allah doesn't exist.Tell me ,if Allah exist,there would be neither suffering nor pain.I can't imagine a loving Allah who would allow all of this things.'

The customer thought for a moment bit but didn't respond because he didn't want to start an argument.The barber finished his job and the customer left the shop.

Just after he left the barbershop,he saw a man in the street with long,stringy,dirty hair and untrimmed beard.He looked dirty and unkempt.

The customer turned back and entered the barber shop again and he said to the barber,'you know what?Barber also do not exist.' 'How can you say that?Asked and I'm a barber.And I just worked on you', he exclaimed.

'Barbe don't exist because if they did,there would be no people with dirty long hair and untrimmed beard,like that man outside.' 'Ah but barber do exist!That what happen when people do not come to me.'

'Exactly!',affirmed the customer.'That is the point!Allah, too does exist!That is happen when people do not go to him and don't look for him for help.That is why there is so much pain and suffering in the world.'
