In the name of Allah, the Most Gracious, the Most Merciful. What are the types of acts of worship directed to other than Allah?

Worship is submission and humility to God. Scholars have defined it as: "a comprehensive term for everything that God loves and approves of, including apparent and hidden sayings and actions." Examples include prayer, supplication (du'a), swearing oaths, slaughtering, and prostration. Whoever directs any of these acts of worship to other than God has committed an act of disbelief (kufr) or polytheism (shirk), as narrated in the story of the man who entered Hellfire because he offered a fly to an idol, and another who entered Paradise for refusing to do so. The types of worship are numerous, and they belong exclusively to God Almighty alone.
