حَدَّثَنَا عَلِيُّ بْنُ عَاصِمٍ أَخْبَرَنَا مُعَاوِيَةُ بْنُ عَمْرِو بْنِ غَلَابٍ عَنِ الْحَكَمِ بْنِ عَبْدِ اللَّهِ بْنِ الْأَعْرَجِ قَالَ كُنْتُ عِنْدَ ابْنِ عَبَّاسٍ فِي بَيْتِ السِّقَايَةِ وَهُوَ مُتَوَسِّدٌ بُرْدًا لَهُ قَالَ فَقُلْتُ يَا أَبَا عَبَّاسٍ أَخْبِرْنِي عَنْ عَاشُورَاءَ قَالَ عَنْ أَيِّ بَالِهِ قَالَ قُلْتُ عَنْ صِيَامِهِ قَالَ إِذَا أَنْتَ أَهْلَلْتَ الْمُحَرَّمَ فَاعْدُدْ تِسْعًا ثُمَّ أَصْبِحْ يَوْمَ التَّاسِعِ صَائِمًا قُلْتُ كَذَا كَانَ يَصُومُهُ مُحَمَّدٌ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ نَعَمْ
مسند امام احمد بن حنبل · Hadith 2214
It was narrated that al- Hakam bin 'Abdullah bin al-A'raj said: I was with Ibn 'Abbas (RA) in the house where they provide water, and he was using a cloak of his as a pillow. I said: O Ibn 'Abbas, tell me about 'Ashoora'. He said: What about it? I said: About fasting it. He said: When you see the new moon of Muharram, count nine (days), then fast on the ninth day. I said: Is that how Muhammad (PBUH)fasted it? He said: Yes.
