[Allâh's Messenger (ﷺ) said, "There is no ' Adwa (no disease is conveyed from the sick to the healthy without Allâh's Permission), nor Șafar, nor Hâmah."] A bedouin stood up and said, "Then what about my camels? They are like deer on the sand, but when a mangy camel comes and mixes with them, they all get infected with mange." The Prophet (ﷺ) said, "Then who conveyed the (mange) disease to the first one?" [7:615-O.B]
