Abdullah bin As-Sa'di narrated that he came to 'Umar bin Al-Khattab during his Caliphate and 'Umar said to him:
I heard that you do some jobs for the people but when payment is given to you, you do not like it. I said: Yes (that is so). He said: Why do you do that? I said: I have horses and slaves and well off, and I wanted my work to be an act of charity toward the Muslims. 'Umar said to him: Do not do that. I used to want the same thing as you. The Messenger of Allah used to give me payment and I would say, 'Give it to someone who is more in need of it than I am' until, on one occasion, the Prophet gave me payment and I said: 'Give it to someone who is more in said: Take it and keep it or give it in charity. Wealth when you are not hoping for it and not asking for it, take it, and whatever does not, then do not wish for it. '
