Narrated by Fatima bint Abi Hubaish said to Allah's Apostle, "O Allah'sApostle The snake stirred on the end of the spear and the youth fell dead. No one knew which of them died first, the snake or the youth. That was mentioned to the Messenger of Allah said, "There are jinn in Madina who have become muslim. When you see one of them, call out to it for three days. If it appears after that, then kill it, for it is a shaytan." -Sunna Al-Muwatta Malik 54.33
