Sayyiduna Anas (may Allah be pleased with him) states: The Prophet (peace and blessings be upon him) met a man named Harithah in one of the streets of Madinah. The Prophet (peace and blessings be upon him) asked: "O Harithah! In what state have you entered the morning?" He submitted: "I have entered the morning as a true believer." The Prophet (peace and blessings be upon him) said: "Every faith has a reality, so what is the reality of your faith?" He submitted: "My heart has turned away from the world, so I remain thirsty by day and stay awake by night. I feel as if the Throne of my Lord is before me, and I feel as if I am seeing the people of Paradise enjoying its blessings in Paradise, and the people of Hell being punished in Hell." The Prophet (peace and blessings be upon him) said: "You are right! Hold firmly to it. (You are) a believer whose heart Allah Almighty has illuminated."
Al-Bazzar recorded it. Its chain contains a narrator, Yusuf bin Atiyyah, who is not used as evidence.
