English translation
1592. Narrated 'Aishah رضي الله عنها: The people used to observe Saum (fast) on 'Āshūrā' (the tenth day of the month of Muḥarram) before the fasting of Ramaḍān was made obligatory. And on that day, the Ka'bah used to be covered with a cover. When Allāh made the fasting of the month of Ramaḍān compulsory, Allāh's Messenger ﷺ said, "Whoever wishes to observe Saum (fast) (on the day of 'Āshūrā') may do so; and whoever wishes to leave it can do so."
