We must be mindful of our attachment to the world and be generous in spending our wealth on Allah's path, for this is the only way to receive a great reward in the Hereafter. Greed and meanness will harm us in the long run, and disasters from Allah are a reminder that our time in this world is limited. Believers are aware of this and use their wealth as a means to draw closer to Allah, understanding that true praise lies in His sight. The Prophet Sulaiman (peace be upon him) is the finest example of someone who had great wealth and assets, but used them to further Allah's path.
Believers, who have faith in Allah and spend their wealth on His path, will be rewarded with Allah's mercy and Paradise in the Hereafter. These people have chosen the infinite wealth and salvation of the Hereafter over the transient wealth of this world, thus making the best possible bargain.
