(37) باب قَتْلِ الْحَيَّاتِ وَغَيْرِهَا
Abu Sa'id Khudri reported Allah's Messenger having said:
There is a group of jinns in Medina who accepted Islam, so he who would see anything from these occupants should warn him three times; and if he appears after that, he should kill him for he is a satan.
