عَنْ أَبِي هُرَيْرَةَ قَالَ: سَمِعْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَقُولُ: «لَا طِيَرَةَ وَخَيْرُهَا الْفَأْلُ» قَالُوا: وَمَا الْفَأْلُ؟ قَالَ: «الْكَلِمَةُ الصَّالِحَة يسْمعهَا أحدكُم»

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.
