Sahih Muslim 1133 a
Hakam b. 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.وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا وَكِيعُ بْنُ الْجَرَّاحِ، عَنْ حَاجِبِ بْنِ عُمَرَ، عَنِ الْحَكَمِ بْنِ الأَعْرَجِ، قَالَ انْتَهَيْتُ إِلَى ابْنِ عَبَّاسٍ - رضى الله عنهما - وَهُوَ مُتَوَسِّدٌ رِدَاءَهُ فِي زَمْزَمَ فَقُلْتُ لَهُ أَخْبِرْنِي عَنْ صَوْمِ عَاشُورَاءَ . فَقَالَ إِذَا رَأَيْتَ هِلاَلَ الْمُحَرَّمِ فَاعْدُدْ وَأَصْبِحْ يَوْمَ التَّاسِعِ صَائِمًا . قُلْتُ هَكَذَا كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَصُومُهُ قَالَ نَعَمْ .
