وحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، حَدَّثَنَا وَكِيعُ بْنُ الْجَرَّاحِ ، عَنْ حَاجِبِ بْنِ عُمَرَ ، عَنِ الْحَكَمِ بْنِ الْأَعْرَجِ ، قَالَ : انْتَهَيْتُ إِلَى ابْنِ عَبَّاسٍ رَضِيَ اللَّهُ عَنْهُمَا وَهُوَ مُتَوَسِّدٌ رِدَاءَهُ فِي زَمْزَمَ ، فَقُلْتُ لَهُ أَخْبِرْنِي عَنْ صَوْمِ عَاشُورَاءَ ، فَقَالَ : " إِذَا رَأَيْتَ هِلَالَ الْمُحَرَّمِ فَاعْدُدْ ، وَأَصْبِحْ يَوْمَ التَّاسِعِ صَائِمًا ، قُلْتُ : هَكَذَا كَانَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَصُومُهُ ، قَالَ : نَعَمْ ،
Hakam bin al-'Araj reported: I went to Ibn 'Abbas (Allah be Pleased with both of them) and he was reclining using his mantle as a pillow near the fountain of Zamzam. I said to him: Tell me about fasting on Ashura. He said: When you see the new moon of Muharram then count the (days) and observe fast on the 9th. I said to him: Is it how the Messenger of Allah (ﷺ) observed the fast? He said: Yes.
