6ـ وَعَنْهُ عَنْ مُحَمَّدِ بْنِ عِيسَى قَالَ حَدَّثَنَا مُحَمَّدُ بْنُ أَبِي عُمَيْرٍ عَنْ زَيْدٍ النَّرْسِيِّ قَالَ سَمِعْتُ عُبَيْدَ بْنَ زُرَارَةَ يَسْأَلُ أَبَا عَبْدِ الله (عَلَيْهِ السَّلاَم) عَنْ صَوْمِ يَوْمِ عَاشُورَاءَ فَقَالَ مَنْ صَامَهُ كَانَ حَظُّهُ مِنْ صِيَامِ ذَلِكَ الْيَوْمِ حَظَّ ابْنِ مَرْجَانَةَ وَآلِ زِيَادٍ قَالَ قُلْتُ وَمَا كَانَ حَظُّهُمْ مِنْ ذَلِكَ الْيَوْمِ قَالَ النَّارُ أَعَاذَنَا الله مِنَ النَّارِ وَمِنْ عَمَلٍ يُقَرِّبُ مِنَ النَّارِ.

6. It is narrated from him (narrator of previous Hadith) from Muhammad ibn ‘Isa who has said that narrated to us Muhammad ibn abu ‘Umayr from Zayd al-Narsiy who has said the following: “I heard Zurarah asking abu ‘Abd Allah, ‘Alayhi al-Salam, about the fast on the day of ‘Ashura’. He (the Imam) said, ‘Whoever fasts that day, his share for such fast is like the share of ibn Marjanah and the family of Ziyad.’ I then asked, ‘What was their share of that day ? 5 He (the Imam) said, ‘It is the fire, I seek protection with Allah against it and against the deeds that take one closer to the fire.’”
