Silsilah as-Sahihah 841 — Intending obligatory fast after dawn if

It is narrated from Nafi‘ that Sayyiduna ‘Abdullah bin ‘Umar (may Allah be pleased with them both) related to him that he heard the Messenger of Allah (peace and blessings be upon him) say on the Day of ‘Ashura: “The people of the Age of Ignorance used to fast on this day. Now, whoever wishes to fast on it, let him fast, and whoever wishes to leave it, let him leave it.”
