1. My father narrated to me from all of my scholars, from Sa’d ibn ‘Abdillāh, from Muḥammad ibn Ḥusain ibn Abil Khaťťāb, from Abī Dāwūd Al-Mustariq, from some of our companions, who said: Abū ‘Abdillāh (Imam Sādiq ) said: ‘Ali ibn Ḥusain (Imam Sajjād ) cried over his father, Ḥusain ibn ‘Ali , for twenty years – or forty years – and whenever food was brought to him, he would cry over Ḥusain . One day his servant said to him, “May I sacrifice myself for you, O son of the Messenger of Allāh! I am afraid that you will die (from grief).” He (Imam Sajjād ) replied, “I only complain of my distress and grief to Allāh, and I know from Allāh what you do not know’ (12:86). Verily whenever I remember the killing of the children of Fāťimah (s.a.), I am choked with tears over them.”
