Mishkat al-Masabih 23 Medicine and Spells كتاب الطب والرقى 64

وَعَنْ جَابِرٍ قَالَ: سَمِعْتُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «لَا عَدْوَى وَلَا صَفَرَ وَلَا غُولَ» . رَوَاهُ مُسلم

Jabir told that he heard the Prophet say: “There is no infection, no serpent in a hungry belly, and no ghoul.”* Muslim transmitted it. * I have used the English word derived from the Arabic ghul. It was used of a creature which was a type of jinni or devil which was believed to appear to people in various forms and lead them astray in the desert and cause their destruction.
