Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) gave an order to Abu Taybah, and he placed the cupping instruments at sunset. Then he gave him the order at the time the fasting person breaks his fast, and he cupped him. Then he asked him: "How much is your levy (kharaj)?" He replied: "Two sa'." So the Prophet (peace and blessings be upon him) remitted one sa'.
Al-Tabarani recorded it in al-Mu'jam al-Awsat, and its narrators are the narrators of the Sahih.
