حَدَّثَنَا عُثْمَانُ بْنُ عُمَرَ حَدَّثَنَا ابْنُ أَبِي ذِئْبٍ عَنْ سَعِيدِ بْنِ خَالِدِ بْنِ عَبْدِ اللَّهِ بْنِ قَارِظٍ عَنْ أَبِي عُبَيْدٍ مَوْلَى عَبْدِ الرَّحْمَنِ بْنِ أَزْهَرَ قَالَ رَأَيْتُ عَلِيًّا وَعُثْمَانَ رَضِيَ اللَّهُ عَنْهُمَا يُصَلِّيَانِ يَوْمَ الْفِطْرِ وَالْأَضْحَى ثُمَّ يَنْصَرِفَانِ يُذَكِّرَانِ النَّاسَ قَالَ وَسَمِعْتُهُمَا يَقُولَانِ إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ نَهَى عَنْ صِيَامِ هَذَيْنِ الْيَوْمَيْنِ قَالَ وَسَمِعْتُ عَلِيًّا يَقُولُ نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنْ يَبْقَى مِنْ نُسُكِكُمْ عِنْدَكُمْ شَيْءٌ بَعْدَ ثَلَاثٍ
مسند امام احمد بن حنبل · Hadith 510
It was narrated that Abu 'Ubaid, the freed slave of 'Abdur- Rahman bin Azhar, said: I saw 'Ali and "Uthman (RA) on the day of ( Eid ) al-Fitr and (Eid) al-Adha; they prayed, then when they finished they reminded the people. I heard them saying: The Messenger of Allah (PBUH) forbade fasting on these two days. He said: And I heard 'Ali say: The Messenger of Allah (PBUH) forbade anything of the sacrificial meat to be left after three days.
