Achieving pure slavery to Allah Almighty
By freeing people from the false beliefs; such as idolatry, worshipping the stars and planets, magic and sorcery, guiding the society to worship Allah alone, and apply this belief in their lifeAllah said ( interpretation of the meaning ) : { And they were not commanded except to worship Allah, [being] sincere to Him in religion, inclining to truth, and to establish prayer and to give zakah. And that is the correct religion.} Quran ( 98 : 5 )
