21. My father narrated to me from Muḥammad ibn Ḥasan (ibn ‘Ali) ibn Mahziyār, from his father, from ‘Ali ibn Mahziyār, from Ḥasan ibn Sa’īd, from Faďālah ibn Ayyūb, from Dāwūd ibn Farqad, who said: I heard Abā ‘Abdillāh (Imam Sādiq عليه السلام) say: The killer of Ḥusain ibn ‘Ali عليه السلام was conceived illegitimately and the killer of Yaḥyā ibn Zakariyyā عليه السلام was (also) conceived illegitimately. When Ḥusain ibn ‘Ali عليه السلام was killed, the heavens turned red for one year. The heavens and the earth have (only) wept over Ḥusain ibn ‘Ali عليه السلام and Yaḥyā ibn Zakariyyā عليه السلام, and the heavens weep by becoming red.
