Ibn Abbas (may Allah be pleased with them both) said: The Messenger of Allah (peace and blessings be upon him) fasted the day of Ashura and ordered that it be fasted. The Companions said: O Messenger of Allah, it is a day that the Jews and Christians hold in great esteem. The Messenger of Allah (peace and blessings be upon him) said: "Next year, if Allah wills, we will fast the ninth." But before the next year came, the Messenger of Allah (peace and blessings be upon him) passed away.
