Hazrat Mirza Ghulam Ahmad, the Promised Messiah (as) says:

“A God-fearing person can find more happiness in a hut, than a worldly person, who is a slave to greed and avarice, can ever find even in a magnificent castle. The more a worldly person acquires the material wealth of this world, the more they are confronted with afflictions. Hence, remember that true comfort and pleasure is not partaken of by worldly people. Do not be mislead to believe that abundant wealth, expensive and elegant clothing, and fine foods can bring happiness. Absolutely not. True happiness depends on righteousness alone.” (Malfuzat, vol. 1, p. 280)
