Narrated Abdullah ibn Umar: Zayd ibn Aslam said: Abdullah ibn Umar entered upon Mu'awiyah. He asked: (Tell me) your need, AbuAbdurRahman. He replied: Give (the spoils) to those who were set free, for I saw the first thing the Messenger of Allah (ﷺ) did when anything came to him was to give something to those who had been set free
