Real happiness and peace can be found in submitting to the commands of the Creator and the Sustainer of thisworld. 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 Quran¹, he will have a difficult life, and We will raise him up blind on the Day of Judgment.}(Quran, 20:124)

This may explain why some people commit suicide while the 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

Please refer to the pamphlet entitled "The Sword of Islam." This pamphlet discusses how Islam was spread by the sword of truth and not by the sword of steel (i.e. force). In this pamphlet, you can read the thoughts and feelings of people who have converted to Islam. They are from different countries and have different backgrounds and levels of education.³
