Does living one's life in line with the Qur'an bring happiness?

Excerpt from Mr. Adnan Oktar's Live Conversation on A9TV dated February 19th, 2018

VTR: Does living one's life in line with the Qur'an bring happiness?

ADNAN OKTAR: Look at you. You are an exceptionally handsome young man. May God honor you with His heaven and a His beautiful physical presence. Your face is radiant with divine light, masha'Allah. Living one's life in line with the Qur'an is the only way to happiness. It is impossible to attain happiness in any other way. In Surah al-Isra', Almighty God puts emphasis on this issue. I seek refuge in God from satan: "This Qur’an guides to the most upright Way and gives good news to the believers who do right actions that they will have a large reward." (Surah al-Isra', 9) We see this great beauty like this in the Qur'an. Therefore, it is an utterly vital issue. This is also what is meant by "Only in the remembrance of God can the heart find peace." God is remembered through the Qur'an. "Only in the remembrance of God can the heart find peace."  (Surah ar-Ra'd, 28) One can find happiness only by reading and abiding by the Qur'an. Happiness, comfort and mirth is impossible to attain any other way. But the most important of them all is to love God sincerely and wholeheartedly.
