†ĎAbd Allāh ibn Muhammad reports from Hishām ibn Yusuf, from Muíammar, from al-Zuhri, from Abu Maslamah, from Abu Hurayrah that he said: The Prophet (S) said: There is neither contagion, nor paleness, nor vermin. An Arab said: O The Messenger of Allah, what is the matter with the she-camels that being in the sand like the deers, and then when being associated with the mange camel, they be infected with mange? The Messenger of Allah replied: Who has infected the former.
†Abu Salamah also reports that he heard Abu Hurayrah say: The Prophet (S) said: No diseased should be brought unto a healthy one. Then Abu Hurayrah denied his first hadith, and we said: Havenít you narrated that no contagion is there? Thereat he jargonized in the Abyssinian language. Abu Salamah said: I never saw him forgetting any other hadith than it.
†So, that is, O intelligent reader, the Sunnah of the Messenger, or say, what is ascribed to the Messenger. As Abu Hurayrah that he has no knowledge of his former hadith, but he was told by some news-teller, and another time when he is confronted with his contradiction, he canít give a reasonable reply but only jargonizes in the Abyssinian dialect so as no one be able to understand his speech.
