The Messenger of Allah (ﷺ) as saying : There is no infection, no evil, omen or serpent, in a hungry belly and no hamah. A nomadic Arab asked: How is it that when camels are in the sand as if they were gazelles and a mangy camel comes among them and it gives them mange ? He replied: Who infected the first one ?

Ma'mar, quoting al-Zuhri said: A man told me that Abu Hurairah narrated to him saying that he heard the Prophet (ﷺ) say: A diseased camel should not be brought with a healthy camel to drink water. He said: The man then consulted him and said: Did you not tell us that Prophet (ﷺ) had said: There is no infection, no serpent in a hungry belly and no hamah? He replied: I did not transmit it to you. Al-Zuhri said: Abu Salamah said: He had narrated it and I did not hear that Abu Hurairah had ever forgotten any tradition except this one.
