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]
{أَلَا بِذِكْرِ اللَّهِ تَطْمَئِنُّ الْقُلُوبُ} [الرعد:٢٨]
Transliteration: 'Alā Bidhikri Allāhi Taţma'innu Al-Qulūbu
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,[1] he will have a hard life, and We will raise him up blind on the Day of Judgment.} [Quran 20:124]
{وَمَنْ أَعْرَضَ عَن ذِكْرِي فَإِنَّ لَهُ مَعِيشَةً ضَنكًا وَنَحْشُرُهُ يَوْمَ الْقِيَامَةِ أَعْمَىٰ} [طه:١٢٤]
Transliteration: Wa Man 'A`rađa `An Dhikrī Fa'inna Lahu Ma`īshatan Đankāan Wa Naĥshuruhu Yawma Al-Qiyāmati 'A`má
This may explain why some people commit suicide while they enjoy the material comfort money can buy. For example, look at Cat Stevens (now Yusuf Islam), formerly a famous pop singer who used to earn sometimes more than $150,000 a night. After he converted to Islam, he found true happiness and peace, which he had not found in material success.[ 2]
