وَحَدَّثَنِي عَنْ مَالِكٍ، أَنَّهُ بَلَغَهُ أَنَّ عُمَرَ بْنَ الْخَطَّابِ، أَرْسَلَ إِلَى الْحَارِثِ بْنِ هِشَامٍ أَنَّ غَدًا، يَوْمُ عَاشُورَاءَ فَصُمْ وَأْمُرْ أَهْلَكَ أَنْ يَصُومُوا ‏.‏

Yahya related to me from Malik that he had heard that Umar ibnal-Khattab had sent (the following message) to al-Harith ibn Hisham,''Tomorrow is the day of Ashura, so fast (it) and tell your family tofast (also)." Translation Not Available
