Yazid bin Abdullah bin al-Shukhair (may Allah be pleased with him) narrates that we were sitting in the (neighborhood) of Mirbad in Basra when a Bedouin came who had a piece of leather or a piece of hide with him. He said: This document was written for me by the Prophet Muhammad (peace and blessings be upon him). Abu al-Ala says: I took it and began to read it before the people, and it was written in it: In the name of Allah, the Most Gracious, the Most Merciful. This document is from Muhammad, the Messenger of Allah, to the Banu Zuhayr bin Aqish. If you establish prayer, pay zakat, give the fifth from the spoils of war, and give the share of the Prophet (peace and blessings be upon him) and the share of the chosen one (safi), then you will be under the protection of Allah and His Messenger. Abu al-Ala says: We asked him: Have you heard anything from the Messenger of Allah (peace and blessings be upon him)? He said: I heard the Messenger of Allah (peace and blessings be upon him) say: Fasting in the month of Ramadan and fasting three days in every month removes malice from the heart. He says: I asked him: Did you yourself hear this from the Messenger of Allah (peace and blessings be upon him)? He replied: Do you think I would lie about the Messenger of Allah (peace and blessings be upon him)? He says: Then he took the document and turned his back and left. This hadith is from Ahmasi, but the wording is similar.
