@islamic_guidance_: The Prophet ﷺ was asked about fasting the day of 'Ashura, and he said, "It will expiate the sins of the past year." [Sahih Muslim 1162] 9th of Muharram = Wednesday June 24 10th of Muharram = Thursday June 25 11th of Muharram = Friday June 26 Fast the 10th if you can, alongside the 9th or 11th as well.
