There is a narration in Luhoof of Sayed ibn Tawus that a man was seen sometime after the tragedy of Karbala weeping at the Kaaba begging Allah for forgiveness but said he didn’t think he would be forgiven.
A man saw him and said Allah is the all merciful surely he will forgive you.
The man who was crying said come close so I can tell you my story. I was one of the 50 men who carried the sacred head of Hussain to Sham. At night we pulled out the head and start drinking wine. That night it started lightening and I saw the gates of the heavens open and Adam, Nuh, Ishaq, Ismail, and Prophet Muhammad all came down with angel Jibrael and the other angels. They all picked up the head of Hussain and began embracing it, kissing it and all began to weep and cry for Imam Hussain.
