It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that in a village located two or four farsakhs from Madinah Munawwarah, on the day of Ashura, the Prophet (peace and blessings be upon him) sent this message: "Whoever has eaten or drunk anything since morning should not eat or drink for the rest of the day, and whoever has not eaten anything until now should complete his fast (i.e., refrain from eating and drinking until Maghrib)."
