It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that the Prophet (peace and blessings be upon him) said: Whenever a person leaves his house, there are two flags at his door. One flag is in the hand of an angel and the other is in the hand of Satan. If he goes out for an act that pleases Allah, the angel takes his flag and accompanies him, and he remains under the angel’s flag until he returns home. And if he goes out for an act that displeases Allah, Satan takes his flag and accompanies him, and he remains under Satan’s flag until he returns home.
