Narrated to us Abu Kurayb, narrated to us Abu Usamah, from Al-Walid — meaning Ibn Kathir — narrated to me Nafi', that Abdullah ibn Umar, may Allah be pleased with them both, narrated to him that he heard the Messenger of Allah, peace and blessings be upon him, say on the day of Ashura: "Indeed, this is a day that the people of the Jahiliyyah used to fast. So whoever wishes to fast it, let him fast it, and whoever wishes to leave it, let him leave it." And Abdullah, may Allah be pleased with him, would not fast it unless it coincided with his regular fasting.
