6 وَ عَنْهُ عَنْ مُحَمَّدِ بْنِ الْحُسَيْنِ عَنْ صَفْوَانَ بْنِ يَحْيَى عَنْ دَاوُدَ بْنِ فَرْقَدٍ عَنْ أَبِي عَبْدِ اللَّهِ (ع) قَالَ كَانَ الَّذِي قَتَلَ الْحُسَيْنَ بْنَ عَلِيٍّ (ع) وَلَدَ زِناً وَ الَّذِي قَتَلَ يَحْيَى بْنَ زَكَرِيَّا وَلَدَ زِنًا

6. Muḥammad ibn Ja’far Al-Qurashi Al-Razzāz narrated to me from Muḥammad ibn Ḥusain (ibn Abil Khaťťāb), from Safwān ibn Yaḥyā, from Dāwūd ibn Farqad, who said: Abū ‘Abdillāh (Imam Sādiq ) said: The killer of Ḥusain ibn ‘Ali was conceived illegitimately and the killer of Yaḥyā ibn Zakariyyā was (also) conceived illegitimately.
