I heard Abā ‘Abdillāh (Imam Sādiq (a.s.)) say: (One day) while Ḥusain ibn ’Ali (a.s.) was with the Messenger of Allāh (s.a.a.w.), Jabra`īl came to him and asked, “O Muḥammad! Do you love him?” “Yes,” the Prophet (s.a.a.w.) replied. “Verily your nation will kill him,” Jabra`īl said. So the Messenger of Allāh (s.a.a.w.) was extremely grieved. Jabra`īl asked, “O Messenger of Allāh! Would you like me to show you the land on which he will be killed?” “Yes,” the Prophet (s.a.a.w.) replied. Then the land (between Karbalā and Madīnah) sunk within the ground and the place where the Messenger of Allāh (s.a.a.w.) was sitting (in Madīnah) and the land on which Ḥusain (a.s.) was killed attached to one another like this – and Imam (a.s.) put his two index fingers together. Imam (a.s.) added: Jabra`īl then picked up some of the dust (of Karbalā) with his wing and gave it to the Messenger of Allāh (s.a.a.w.). Thereafter, the earth returned to the way it was in less than a blink of an eye. The Messenger of Allāh (s.a.a.w.) (while holding the dust of Karbalā in his hand) said to it, “O dust! You are blissful, and blissful is he who will be killed on you!”
