they are referred to by medical scientists as "bacteria repellent," and they kill many disease germs. Those germs cannot remain alive or have any effect on the human body in the presence of the bacteria repellent. There is a property in one of the fly's wings, which is that it attracts bacteria to itself. Therefore, if a fly falls into a drink or food and deposits the germs clinging to its extremities into that drink, the nearest and first repellent to those germs is the bacteria repellent that the fly carries within its body, near one of its wings. Thus, if there is a disease, its remedy is close by, and immersing the entire fly and discarding it is sufficient to kill the germs that were clinging and sufficient to nullify their effect." I read long ago in this magazine a comprehensive study on this topic by Dr. Saʿīd al-Suyūṭī (Volume of the first year), and I read a statement in last year's volume (p. 503) by the doctors Maḥmūd Kamāl and Muḥammad ʿAbd al-Munʿim Ḥusayn, quoting from the "Majallat al-Azhar." Then I came across issue (82) of the Kuwaiti "Majallat al-ʿArabī" on page 144 under the title: "You Ask, We Answer," written by someone named ʿAbd al-Wārith Kabīr, as a response to a question about the authenticity and weakness of this ḥadīth. He said: "As for the ḥadīth of the fly, and what is in its wings of disease and cure, it is a weak ḥadīth, rather it is intellectually fabricated. It is well known that flies carry germs and filth... and no one has ever said that in one wing of the fly there is disease and in the other a cure, except the one who fabricated or invented this ḥadīth. If this were true, modern science, which decisively identifies the harms of flies and urges combating them, would have revealed it." In the discussion, there is a need to uncover the interpolation and ignorance to defend the ḥadīth of the Messenger of Allāh (ṣallá Allāhu ʿalayhi wa-sallam), and to protect it from being disbelieved by those who might be deceived by the embellishment of speech!
