" When we grasp that all of this world’s blessings are a
gift of Allah and are thankful for them, we please Allah. As
a result, we are always aware that the beauty, blessings,
and good things around us come from Him.
However, those who deny Allah do not see this truth.
Instead, they ignore Him and appease their desires and
passions. As they enjoy more and more of these blessings,
their discontent also increases, because they are consumed
by the maniacal desire to possess everything.
Instead of being content with what they have, they are
unhappy until they get even more. And as a result, they can
never fully appreciate the countless blessings and limitless
potentials that they already possess. For example, they
may have a fine car but become dissatisfied with it as soon
as a new model comes out. They believe that going on
vacation will end all of their difficulties; however, the slightest
setback causes them misery and anxiety. They do not
try to overcome their difficulties with patience and submission
to destiny, but become pessimistic and return even
more anxious and disappointed. Even if they had enjoyed
themselves, their pleasure is only temporary; the following
anxiety is far more enduring. "
