The meaning of [هُدًى لِّلْمُتَّقِينَ] is not what you understood. The holy Quran is a complete guidance and beneficial for those who want to become Muttaqi [pious]. Get yourself busy in good deeds and keep on it doing with full sincerity and save yourself from all the forbidden things. Then it shall bring the fear of Allah in your heart and the fear of Allah shall increase in you.
