Sunan al-Nasa'i The Book of Zakah Abd al-Muttalib b. Rabi'ah b. al-Harith Abdullah bin Wahb عبد الله بن وهب بن مسلم القرشي al-Zuhri ابن شهاب الزهري‎, محمد بن مسلم Amr bin Sawad عمرو بن سواد Yonus bin Yazid bin Abi al-Nijad يونس بن يزيد بن أبي النجاد “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 take during the time of the Messenger of Allah, and I said what you have said, but the Messenger of Allah said to me: “If you are given something without asking for it, then keep (some) and give (some) in charity.”‘ https://parallelquran.com/hadith/sunan-al-nasai-2609/
