An 18th century Ottoman dental manuscript depicts Jinn causing toothaches which explains them employing bacteria to harm humans, if given opportunity. Prophet Muhammad ﷺ advised certain measures before sleeping at night: “Cover the vessels, tie the water-skins, close the doors, extinguish the lamps, for indeed the vermin may drag away the wick, causing a fire for the inhabitants of the house.” Implying devils possibly affecting our food and drink with bacteria through their agents like roaches, rats, snakes or lizards that carry impurities. Avoiding such precautions may cause our food to be contaminated such as the recent case of 15 members of a Pakistani family becoming sick and one dead after lizard contaminated their food. In medieval times Bubonic Plague called Black Death spread in Europe and the East like fire causing death of millions. The major source was rat fleas that crept in to people’s homes affecting water and food as well as affectees fleeing in to non-affected territories. Thus the Prophet ﷺ said: "Plague is the piercing of your enemies from among the jinn." also "If you hear of an outbreak of plague in a land, do not enter it; if the plague breaks out in a place while you are in it, do not leave."
The Prophet ﷺ advised: “Wash the vessel dog has drunk from seven times: first or last of them with mud. And when the cat drinks... wash it once.” A 48 year old man in US caught an infection through dog’s saliva that resulted in amputation of his legs, hands and parts of his face. Capnocytophaga canimorsus is a bacterial pathogen found in healthy dogs and cats but primarily transferred in to human through dogs. Greg Manteufel, who was not bitten or scratched, picked up the bacteria through a dog lick.
