The Messenger of Allah ﷺ said: Beware of the wages of a distributor of booty (qusamah). We asked: What is qusamah (wages of a distributor)? He said: It means a thing which is shared by the people, and then it is reduced.  

أَخْبَرَهُ أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ إِيَّاكُمْ وَالْقُسَامَةَ قَالَ فَقُلْنَا وَمَا الْقُسَامَةُ قَالَ الشَّىْءُ يَكُونُ بَيْنَ النَّاسِ فَيَجِيءُ فَيَنْتَقِصُ مِنْهُ  

Ata' reported a similar tradition (to No 2777) from the Prophet ﷺ. This version adds: a man is appointed on groups of people, and takes (wages) from the share of this, and from the share of this.  

عَنِ النَّبِيِّ ﷺ نَحْوَهُ قَالَ الرَّجُلُ يَكُونُ عَلَى الْفِئَامِ مِنَ النَّاسِ فَيَأْخُذُ مِنْ حَظِّ هَذَا وَحَظِّ هَذَا
