Hazrat Imam Hussain A.S Said:
Those who worship God for the hope of gaining ,
they're not real worshippers ,they're merchants.
Those who worship God out of fear ( of punishment ) , they're slaves.
And those who worship God to be grateful towards their creator ,
they are the free people , and their worship is a real one.
(Bihar al- Anwar, Vol. 78 , P. 117)
