Abstract
The texts reflecting the scientific sign are: The prophet (may peace be upon him) hadiths: Abu Huraira reported the Messenger of Allah (may peace be upon him) to have said: When the dog licks a utensil belonging to any one of you, (the thing contained in it) should be thrown away and then (the utensil) should be washed seven times.
This hadith has been transmitted by another chain of transmitters in which there is no mention of” throwing away
Abu Huraira reported: The Messenger of Allah (may peace be upon him) said: When the dog drinks out of a container belonging to any one of you, he must wash it seven times.
Abu Huraira reported: The Messenger of Allah (may peace be upon him) said: The purification of the utensil belonging to any one of you, after it is licked by the dog, lies in washing it seven times, using sand for the first time.
Hammam Munabbih reported: Of the a hadith narrated by Abu Huraira from Muhammad, the Messenger of Allah (may peace be upon him), one is this: The Messenger of Allah (may peace be upon him) said: The purification of the utensil belonging to one amongst you, after it is licked by the dog, lies in washing it seven times.
Ibn Mughaffal reported: The Messenger of Allah (may peace be upon him) ordered killing of the dogs, and then. said: What about them, i. e. about other dogs? and then granted concession (to keep) the dog for hunting and the dog for (the security) of the herd, and said: When the dog licks the utensil, wash it seven times, and rub it with sand the eighth time.
The scientific fact related to this text is that dog saliva contains pathogens affected human and causes several
diseases. Number of studies showed that dog saliva caused illness to human as prophet Muhammed stated. One study reports a human case of postoperative sinus infection caused by methicillin-resistant Staphylococcus intermedius. This case illustrates the possibility of transmission of antibiotic-resistant bacteria causing infection from dogs to humans. Another case demonstrates for the first time that Staphylocpoccus intermedius, the common commensal and pathogen in dogs, can cause skin abscesses in humans after direct inoculation of this pathogen into the skin and soft tissues. These studies supported by recent study, in which researcher isolated dog bronchopulmonary secretions bacteria. He found many identified microorganisms in the lavage fluid such as Pseudomonas spp., Acinetobacter spp., Stenotrophomonas maltophilia, Micrococcus luteus, Bacillus spp. Micrococcus spp., Staphylococcus spp. and Flavobacterium. In current study the hemolytic activity, which related to the pathogenic potential of two species of oral streptococci processed with dog saliva, was estimated. One of these streptococci is Streptococcus mutans that reside in the human dental plaque and causes dental caries. The other one is Streptococcus pneumoniae that found in human throat and causes pneumonia and other diseases. The hemolytic activity of dog saliva treated- streptococci increased obviously in case of pure dog saliva,then decreased when dog saliva was diluted with water and finally disappeared after six or seven water dilution.
The aspect of scientific sign in the text was taken from three sides; the first side is that dog saliva contains pathogenic supporting factors which increase the hemolytic activity of the Streptococcus pneumonia and Streptococcus mutans. The second side is the obligatory of using sand as the water did not kill the microbes but only reduce it’s pathogenicity. The third one is related to the seven times washing as some microbes pathogenicity did not be affected unless be washed seven times by water.
