4. Al-Hassan ibn Ali al-Hashimiy has narrated from Muhammad ibn Musa from Ya’qub ibn Yazid from al-Hassan ibn Ali al-Washsha’ who has said that narrated to me Najabah ibn al-Harith al-‘ Attar who has said the following: “I once asked abu Ja‘far , about fasting on the day of ‘Ashura’ (tenth of Muharram). He (the Imam) said, ‘It is a discarded fast after the coming of the month of Ramadan, and what is discarded and abandoned is heresy.’ Najabah has said that I then asked abu ‘Abd Allah , after his father about it and he answered me just like the answer of his father. He (the Imam) then said, ‘It is a fast about which there is nothing in the book or an established Sunnah except the Sunnah of the family of Ziyad for their murdering al-Husayn ibn Ali .’”
