Asking God for anything is Actually Unjustified and Wrong.

This is my observation : Asking anything from GOD is unjustice with somebody else on Palnet.

Example.
1) If we are late we pray Train or Bus to be delayed To a point only where we can catch. Now this could be wrong for all other passenger traveling or waiting on other stops. There could be patient in train praying to reach ASAP.
2) We pray God please get me pass marks or some how get me in Merit list.. This is totally wrong How can we ask that its again injustice with others who are appearing in same exams. They worked hard  and deserve better then us.
There could be several other example if we think in others prespective.
