setting

'A'isha (Allah be pleased with her) reported that the Quraish used to fast on the day of Ashura during the pre-Islamic days. The Messenger of Allah (ﷺ) then commanded to fast on that day till (fasting) in Ramadan became obligatory. Then the Messenger of Allah (ﷺ) said

He who wishes to fast should do so, and he who wishes to break it may do so.
