We were created by the Allah swt and He revealed last Divine book Qur'an for the guidance of the whole mankind and He also sent His last and final messenger Prophet Mohammed pbuh as an example for rest of the mankind.
I think if we follow Qur'an and teachings of last Prophet, we all the people in this world will live happily here and may go to heaven after death. May Allah swt guide all of us to follow His last and final Holy book Qur’an and teachings of His Prophet Mohammed pbuh.
