Abdul 'Aziz bin Muhammad al-Daruradi عبد العزيز بن محمد الدراوردي · Jihad (Kitab Al-Jihad)

When the Messenger of Allah (ﷺ) gained booty he ordered Bilal to make a public announcement. He made a public announcement, and when the people brought their booty, he would take a fifth and divide it. Thereafter a man brought a halter of hair and said: Messenger of Allah, this is a part of the booty we got. He asked: Have you heard Bilal making announcement three times? He replied: Yes. He asked: What did prevent you from bringing it?…

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.
