On the authority of Abū Huraira (may Allah be pleased with him), who said: The Messenger of Allah (may the blessings and peace of Allah be upon him) said:
Each person's every joint must perform a charity every day the sun comes up: to act justly between two people is a charity; to help a man with his mount, lifting him onto it or hoisting up his belongings onto it is a charity; a good word is a charity; every step you take to prayers is a charity; and removing a harmful thing from the road is a charity.
It was related by al-Bukhārī and Muslim.
