THE DISEASE AND THE CURE IN THE WINGS OF THE FLY.
PROPHET MUHAMMAD (ﷺ) SAID: "WHEN A FLY FALLS IN THE DRINK OF ONE OF YOU, HE SHOULD FULLY DIP IT AND THEN THROW IT AWAY BECAUSE THERE IS DISEASE IN ONE OF ITS WINGS AND CURE IN THE OTHER"
Many universities in Cairo and Saudi Arabia conduct experiments on the glass of water that a fly fell in it. Chemical analysis discovered more than 10 thousands microbes. Then they fully dip the whole fly in the water and all the microbes vanish. This is because useful bacteria and fungi secrete antibiotics that kill harmful bacteria after falling in the water.
