Real happiness and peace can be found in submitting to the commands of the Creator and the Sustainer of this world. God has said in the Quran: "Truly, in remembering God do hearts find rest." (Quran 13:28) On the other hand, the one who turns away from the Quran will have a life of hardship in this world. God has said: "But whoever turns away from the Quran, he will have a hard life, and We will raise him up blind on the Day of Judgment." (Quran 20:124) This may explain why some people are not happy while they enjoy the material comfort money can buy.
