muslim:1125b – Abū Bakr b. Abū Shaybah And ʾAbū Kurayb > Ibn Numayr

This hadith is narrated on the authority of Hisham with the same chain of transmitters, but he made no mention in the first part of the hadith that the Messenger of Allah ﷺ used to observe fast, and said about the second part that he abandoned the (fast) of Ashura, and he who wished observed the fast and who wished otherwise abandoned it, and he did not hold it as the words of the Messenger of Allah ﷺ as mentioned in the narration transmitted by Jarir.  

مسلم:١١٢٥b – وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَأَبُو كُرَيْبٍ قَالاَ حَدَّثَنَا ابْنُ نُمَيْرٍ عَنْ هِشَامٍ بِهَذَا الإِسْنَادِ وَلَمْ يَذْكُرْ فِي أَوَّلِ الْحَدِيثِ

وَكَانَ رَسُولُ اللَّهِ ﷺ يَصُومُهُ وَقَالَ فِي آخِرِ الْحَدِيثِ وَتَرَكَ عَاشُورَاءَ فَمَنْ شَاءَ صَامَهُ وَمَنْ شَاءَ تَرَكَهُ وَلَمْ يَجْعَلْهُ مِنْ قَوْلِ النَّبِيِّ ﷺ كَرِوَايَةِ جَرِيرٍ

That he heard Muawiya bin Abi Sufyan on the day of 'Ashura' during the year he performed the Hajj, saying on the pulpit, "O the people of Medina! Where are your Religious Scholars? I heard Allah's Apostle saying, 'This is the day of 'Ashura'. Allah has not enjoined its fasting on you but I am fasting it. You have the choice either to fast or not to fast (on this day).' "
