حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُوسَى، أَخْبَرَنَا شَيْبَانُ، عَنْ أَشْعَثَ، بْنِ أَبِي الشَّعْثَاءِ عَنْ جَعْفَرِ بْنِ أَبِي ثَوْرٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، - رضى الله عنه - قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَأْمُرُنَا بِصِيَامِ يَوْمِ عَاشُورَاءَ وَيَحُثُّنَا عَلَيْهِ وَيَتَعَاهَدُنَا عِنْدَهُ فَلَمَّا فُرِضَ رَمَضَانُ لَمْ يَأْمُرْنَا وَلَمْ يَنْهَنَا وَلَمْ يَتَعَاهَدْنَا عِنْدَهُ .
