Musnad Abu Ya'la al-Mawsili 109:58

'Abd al-Wahid ibn Ghiyath narrated to us, Abu 'Awanah narrated to us, from Abu Bishr, from Sulayman ibn Qays, from Jabir, who said: The Messenger of Allah (may Allah bless him and grant him peace) sent for Abu Taybah, and he cupped him. He asked him, "How much is your tax?" He said, "Three sa's." So he remitted one sa' for him.
