Ziyadah bin Jahwar narrates: "A letter came to me from the Messenger of Allah (peace and blessings be upon him), in which was written: 'In the name of Allah, the Most Gracious, the Most Merciful. From Muhammad, the Messenger of Allah (peace and blessings be upon him), to Ziyadah bin Jahwar: peace be upon you. I praise before you Allah, besides whom there is no god. To proceed: I remind you of Allah and the Last Day. To proceed: every religion that people follow will certainly be done away with, except Islam; so know this well.'"
