Regarding this subject I also wrote through a friend of mine to Dr. Muhammad M. El-SAMAHY chief of Hadith Dept. in Al-Azhar University CAIRO (Egypt) who has written an article upon this Hadith and as regards medical aspects he has mentioned that the microbiologists have proved that there are longitudinal yeast cells living as parasites inside the belly of the fly and these yeast cells in order to repeat their life-cycle protrude through respiratory tubules of the fly and if the fly is dipped in liquid, these cells burst in the fluid and the content of those cells is an antidote for the pathogens which the fly carries."
Kuhusiana na somo hili pia niliandika kwa rafiki yangu kupitia kwa Dr. Muhammad M. El-SAMAHY, mkuu wa idara ya hadithi ya Chuo Kikuu cha Al-Azhar CAIRO (Misri) ambaye ameandika makala kuhusu Hadithi hii na kuhusiana na taaluma ya uganga amesema kuwa wataalamu wa vijidudu vidogo (microbiologists) wamethibitisha kuwa kuna chembe chachu zenye kukata kwa urefu zinazoishi kama vimelea ndani ya tumbo la nzi na chembe hizi chachu hujichomoza kupitia mishipa ya kupumulia ya nzi na kama mtu akimchovya nzi kwenye kimiminika, chembe hizi hupasuka kwenye kimiminika na vitu vilivyomo kwenye chembe hizi ni viuasumu vya vijidudu ambavyo nzi huvibeba."
