Allah is the best of planners

The planning of the Almighty ( Allah ) is better for you than your own planning

and He could Deprive you from what you ask to test your patience

so let Him see from you a determined patience and you will soon see from Him

what will give you joy. And when you have cleaned the paths of answering

( of supplication ) from the stains of sin ( ie have repented )

and were patient about what He has chosen for you

then everything that happens to you is better for you whether you were given 

or Deprived of what you have requested

~Imaam ibn Al-Jawzee~
