What is Faith?

Knowing God is the greatest worship A man came to the Prophet one day and asked him what the best of all actions was. “The realization of God,” replied the Prophet. The man repeated his question, but the Prophet gave him the same answer. “Prophet of God,” the man said, “I am asking you about actions, whereas you speak of knowledge.” “With knowledge, the smallest action brings greater benefit,” the Prophet told him, “while the greatest of actions brings no benefit, if it is carried out in ignorance.” (JAMI‘ BAYAN AL-‘ILM)
