AbulJuwayriyyah al-Jarmi said: I found a red pitcher containing dinars in Byzantine territory during the reign of Mu'awiyah. A man from the Companions of the Prophet (ﷺ) belonging to Banu Sulaym was our ruler. He was called Ma'an ibn Yazid. I brought it to him. He apportioned it among the Muslims. He gave me the same portion which he gave to one of them. He then said: Had I not heard the Messenger of Allah (ﷺ) say: There is no reward except after taking the fifth (from the booty), I would have given you (the reward). He then presented his own share to me, but I refused.
