This World is transient and the One Whose concern is this World is not equal to the One Whose concern is the Hereafter

Allah tells us about the insignificance of this world and its contemptible adornments which are nothing in comparison to the great and lasting delights which Allah prepared for His righteous servants in the Hereafter. As Allah says:

مَا عِندَكُمْ يَنفَدُ وَمَا عِندَ اللَّهِ بَاقٍ

وَمَا عِندَ اللَّـهِ خَيْرٌ‌ وَأَبْقَىٰ (And that which is with Allah is much better and far more lasting - 28:60). That is the mundane wealth and comforts are all mortal. But the recompense one would get in the Hereafter for the good deeds done in the world is much superior and everlasting as compared to the temporary worldly wealth and comforts. The best of comforts of this world are no match to the bounties of the Hereafter. Then, no matter how attractive mundane comforts are, they are but temporary. As against that, the bounties of the Hereafter will last forever. There is no doubt that anyone having some sense would prefer the better comforts and the ones that will last forever, rather than the short-lived temporary ones.

The sign of prudence is that one does not involve himself too much in worldly matters and cares more for the Hereafter
