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.  

أَصَبْتُ بِأَرْضِ الرُّومِ جَرَّةً حَمْرَاءَ فِيهَا دَنَانِيرُ فِي إِمْرَةِ مُعَاوِيَةَ وَعَلَيْنَا رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ مِنْ بَنِي سُلَيْمٍ يُقَالُ لَهُ مَعْنُ بْنُ يَزِيدَ فَأَتَيْتُهُ بِهَا فَقَسَمَهَا بَيْنَ الْمُسْلِمِينَ وَأَعْطَانِي مِنْهَا مِثْلَ مَا أَعْطَى رَجُلاً مِنْهُمْ ثُمَّ قَالَ لَوْلاَ أَنِّي سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ لاَ نَفْلَ إِلاَّ بَعْدَ الْخُمُسِ لأَعْطَيْتُكَ ثُمَّ أَخَذَ يَعْرِضُ عَلَىَّ مِنْ نَصِيبِهِ فَأَبَيْتُ  

The tradition mentioned above has also been transmitted by ‘Asim bin Kulaib through a different chain of narrators to the same effect.  

عَنْ عَاصِمِ بْنِ كُلَيْبٍ بِإِسْنَادِهِ وَمَعْنَاهُ
