Forty Hadith an-Nawawi
Every joint owes a charity each day
Sahih
On the authority of Abu Hurayrah (may Allah be pleased with him) who said: The Messenger of Allah (peace and blessings of Allah be upon him) said, “Every joint of a person must perform a charity each day that the sun rises: to judge 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. And the good word is a charity. And every step that you take towards the prayer is a charity, and removing a harmful object from the road is a charity.” [Al-Bukhari]
