It was narrated that Ibn As Sa’idi Al-Maliki said: “Umar bin Al Khattab, may Allah be pleased with him, appointed me in charge of the Sadaqah. When I finished collecting it and handed it over to him, he ordered that I be given some payment. I said to him: ‘I only did for the sake of Allah, the Mighty and Sublime, and my reward will be with Allah, the Mighty and Sublime.’ He said: ‘Take what I have given you; I did the same task during the time of the Messenger of Allah صلی اللہ علیہ وآلہ وسلم and I said what you have said, but the Messenger of Allah صلی اللہ علیہ وآلہ وسلم said to me: ‘If you are given something without asking for it, then keep (some) and give (some) in charity.” (Sahih)
