Arabic hadith text
وَحَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ، حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ الْقَطَّانُ، عَنْ مُعَاوِيَةَ بْنِ عَمْرٍو، حَدَّثَنِي الْحَكَمُ بْنُ الأَعْرَجِ، قَالَ سَأَلْتُ ابْنَ عَبَّاسٍ - رضى الله عنهما - وَهُوَ مُتَوَسِّدٌ رِدَاءَهُ عِنْدَ زَمْزَمَ عَنْ صَوْمِ عَاشُورَاءَ . بِمِثْلِ حَدِيثِ حَاجِبِ بْنِ عُمَرَ
Translation
Hakam b. 'Araj reported
I asked Ibn Abbas (Allah be pleased with them) as he was reclining using his cloak as a pillow near Zamzam about fasting on 'Ashura. The rest of the hadith is the same.
