Abu Huraira reported: The Prophet, peace and blessings be upon him, said, “Allah Almighty said: I have divided prayer between Myself and My servant into two halves, and My servant shall have what he has asked for. When the servant says, ‘All praise is due to Allah the Lord of the worlds,’ Allah says: My servant has praised Me. When he says, ‘The Gracious, the Merciful,’ Allah says: My servant has exalted Me. When he says, ‘The Master of the Day of Judgment,’ Allah says: My servant has glorified Me and my servant has submitted to Me. When he says, ‘You alone we worship, You alone we ask for help,’ Allah says: This is between Me and My servant, and My servant will have what he has asked for. When he says, ‘Guide us to the straight path, the path of those whom you have favored, not those who went astray,’ Allah says: This is for My servant, and My servant will have what he has asked for.”
