"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."
(Recorded in al-Bukhari and Muslim)
It was narrated that Abu Hurayrah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings of Allah be upon him) said: "Whoever gives charity equal to a date from good (halal) earnings – for Allaah does not accept anything but that which is good – Allaah will take it in His right hand and tend it for the one who gave it as any one of you tends his foal, until it becomes like a mountain."
Narrated by al-Bukhaari, 1344; Muslim, 1014.
It was narrated from Abu Hurayrah (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: "There is no day on which the people get up but two angels come down and one of them says, 'O Allaah, give in compensation to the one who spends (in charity),' and the other says, 'O Allaah, destroy the one who withholds.'"
Narrated by al-Bukhaari, 1374; Muslim, 1010.
They ask you, [O Muhammad], what they should spend. Say, "Whatever you spend of good is [to be] for parents and relatives and orphans and the needy and the traveler. And whatever you do of good - indeed, Allah is Knowing of it."(2:215)
