Purpose of creation of mankind according to Quran

Muslims believe Quran to be the final word of ALLAH. Whoever studies Quran with intellect and logical reasoning will come to the conclusion that Quran is a divine revelation. there comes a time in life of every human when he/she thinks the reason for the purpose of the creation. why are we born on planet earth and Who is controlling everything? On this quest to search for truth and purpose almost everyone ends up reverting to Islam. Quran has answers to every question that a human mind is unable to answer. ALLAH says in Quran:

"I have created the jinn and humankind only for My worship" 

The Holy Qur'an, Chapter 51, Verse 56

The essential purpose for which the mankind is created is to worship one God, the creator of mankind and universe. Every creation in this world and universe has needs . In islam each and every action of a person can become worship if it is done in accordance with the commands laid doing by ALLAH in Quran or authentic Sunnah. In chapter al-An'aam, ALLAH says:

"Say: 'Surely my prayer, my sacrifice, my living and my dying are for ALLAH, the Lord of all the worlds.' " The Holy Qur'an, Chapter 6, Verse 162

Without the knowledge of the purpose of creation, human beings wander aimlessly. We see that even the most developed nations like Japan, America and Europe have the highest number of suicides. As they don’t have proper satisfaction and answers to the purpose of creation and what will happen after death. Islam is and has the solution for all problems of the world.
