Hadith narrated in Al-Kafi, Chapter 98 Hadith 1

Muhammad ibn Yahya and Ahmad ibn Muhammad have narrated from Muhammad ibn alHassan from Ibrahim ibn Hashim from ‘Amr ibn ‘Uthman from Ibrahim ibn Ayyub from 
‘Amr ibn Shimr from Jabir from abu Ja‘far (a.s.) who has said the following.

 "Once when Amir al-Mu’minin (a.s.) was on the pulpit a serpent entered from one of the doors of the 
mosque. People wanted to kill him. Amir al-Mu’minin (a.s.) asked them to leave him alone. 
They left him alone. The serpent began to crawl to the pulpit. He stretched and saluted to 
Amir al-Mu’minin (a.s.). Amir al-Mu’minin (a.s.) made a gesture to him to wait until the 
sermon is completed. When the sermon was completed he came to him and said, "Who are 
you?" He said, "I am ‘Amr ibn ‘Uthman, your deputy among the Jinns. My father has died 
and he has asked me in his will to come to you and find out your instructions and that is why I 
am here. What do you command me to do and what do you see." Amir al-Mu’minin (a.s.) 
said, "I ask you to be pious before Allah and go back and act as the successor of your father 
among the Jinns. I appoint you as my deputy over them." The narrator has said that ‘Amr then 
said farewell to Amir al-Mu’minin (a.s.) and left as his deputy over the Jinns. I asked The 
Imam (a.s.), may Allah take my soul in service for your cause, does ‘Amr fulfill that 
obligation on him?" He said, "Yes, he does so."
