‘Ali ibn Ḥusain (Imam Sajjād (a.s.)) used to say: Any believer who cries over Ḥusain ibn ‘Ali (a.s.) with (even) one tear running down his cheek will be rewarded by Allāh for that tear; he will be made to dwell in rooms in Paradise where he will stay for long ages. Any believer, who cries over us with (even) one tear running down his cheek because of his grief over the way in which our enemies hurt us in this life, will be rewarded by Allāh for that tear; he will be made to dwell in good settlements in Paradise. And any believer, who cries with (even) one tear running down his cheek because of his suffering from the pain of being hurt in our way, will be kept away from the afflictions of the Day of Judgment by Allāh and he will be safe from Allāh’s Wrath and from Hell. The above Ḥadīth has also been narrated to me through the following chain: My father, and all of my scholars, from Sa’d ibn ‘Abdillāh, from Aḥmad ibn Muḥammad, from Ḥamzah ibn ‘Ali Al-Ash’ari, from Ḥasan ibn Mu’āwiyah ibn Wahab, from someone who narrated to him, from Abī Ja’far (a.s.).
