Sahih Muslim | Book 5 | Chapter 35

Narrated by Salim b. Abdullah b. 'Umar
Salim b. Abdullah b. 'Umar reported on the authority of his father ('Abdullah b. 'Umar) that he had heard 'Umar b. Khattab (Allah be pleased with him) saying: The Messenger of Allah (may peace be upon him) gave me a gift, but I said: Give it to one who needs it more than I. He gave me wealth for the second time but I said: Give it to one who needs it more than I. Upon this the Messenger of Allah (may peace be upon him) said: Take out of this wealth which comes to you without your being avaricious and without begging, but in other circumstance's do not let your heart hanker after it.

Narrated by Salim b. 'Abdullah
Salim b. 'Abdullah reported on the authority of his father that the Messenger of Allah (may peace be upon him) gave to 'Umar b. Khattab some gift. Umar said to him: Messenger of Allah, give it to one who needs it more than I. Upon this the Messenger of Allah (may peace be upon him) said: Take it; either keep it with you or give it as a charity, and whatever comes to you in the form of this type of wealth, without your being avaricious or begging for it, accept it, but in other circumstances do not let your heart hanker after it. And it was on account of this that Ibn 'Umar never begged anything from anyone, nor refused anything given to him.

Narrated by Ibn al-Sa'di Maliki
Ibn al-Sa'di Maliki reported: 'Umar b. Khattab (Allah be pleased with him) appointed me as a collector of Sadaqa. When I had finished that (the task assigned to me) and I handed over that to him (to 'Umar), he commanded me to (accept) some remuneration (for the work). I said: I performed this duty for Allah and my reward is with Allah. He said: Take whatever has been given to you, for I also performed this duty during the time of the Messenger of Allah (may peace be upon him). He assigned me the task of a collector and I said as you say, and the Messenger of Allah (may peace be upon him) said to me: When you are given anything without your begging for it, (then accept it), eat it and give it in charity.
