Hazrat Abu Huraira (may Allah be pleased with him) narrates that one day the Messenger of Allah (peace and blessings be upon him) was sitting among the people in an open place. A man came to the service of the Prophet (peace and blessings be upon him) and asked: O Messenger of Allah! What is the reality of faith? The Prophet (peace and blessings be upon him) replied: The reality of faith is that you believe in Allah, His angels, His books, meeting with Him, and His messengers from your heart. And that you believe from your heart in being raised again after death. The man asked: What is the reality of Islam? The Prophet (peace and blessings be upon him) replied: The reality of Islam is that you worship Allah and do not associate anything with Him, establish the obligatory prayers, pay the obligatory zakat, and fast in Ramadan. He asked: O Messenger of Allah! What is the reality of Ihsan? The Prophet (peace and blessings be upon him) replied: It is that you worship Allah as if you are seeing Him. If you cannot see Him, then (know that) He is seeing you.
