Sayyiduna Abu Hurayrah (may Allah be pleased with him) narrates that the Prophet (peace and blessings be upon him) said: "Whenever anyone goes out of his house, there are two banners at his door: one banner is in the hand of an angel and one banner is in the hand of Satan. If he goes out for something that Allah Almighty loves, the angel follows him with his banner, and he remains continuously under the angel's banner until he returns to his house. And if he goes out for something that angers Allah Almighty, Satan follows him with his banner, and he remains continuously under Satan's banner until he returns home."
Imam Ahmad recorded it, and al-Tabarani in al-Mu'jam al-Awsat; its chain contains Abd al-Rahman bin Abi al-Zinad, whom Imam Malik declared thiqah (trustworthy), while according to one report Imam Ahmad and Yahya bin Ma'in declared him da'if (weak).
