It was narrated that Musa bin Abi 'Aishah said: "I asked Yahya bin Al-Jazzar about this Verse: and know that whatever of spoils of war that you may gain, verily, one-fifth of it is assigned to Allah, and to the Messenger". He said: "I said: 'How much of the Khumus did he Prophet take?' He said: 'One-fifth of the Khumus."'
