Narrated Abu Huraira: Allah's Messenger (ﷺ) said, "No 'Adha." Abu Huraira also said: The Prophet (ﷺ) said, "The cattle suffering from a disease should not be mixed up with healthy cattle (or said "Do not put a patient with a healthy person as a precaution.") Abu Huraira also said: Allah's Messenger (ﷺ) said, "No 'Adha." A bedouin got up and said, "Don't you see how camels on the sand look like deer but when a mangy camel mixes with them, they all get infected with mange?" On that the Prophet (ﷺ) said, "Then who conveyed the (mange) disease to the first camel?"

حَدَّثَنَا أَبُو الْيَمَانِ، أَخْبَرَنَا شُعَيْبٌ، عَنِ الزُّهْرِيِّ، قَالَ حَدَّثَنِي أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ، أَنَّ أَبَا هُرَيْرَةَ، قَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ لاَ عَدْوَى ‏"‏‏.‏ قَالَ أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ سَمِعْتُ أَبَا هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ ‏"‏ لاَ تُورِدُوا الْمُمْرِضَ عَلَى الْمُصِحِّ ‏"‏‏.‏ وَعَنِ الزُّهْرِيِّ، قَالَ أَخْبَرَنِي سِنَانُ بْنُ أَبِي سِنَانٍ الدُّؤَلِيُّ، أَنَّ أَبَا هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏"‏ لاَ عَدْوَى ‏"‏‏.‏ فَقَامَ أَعْرَابِيٌّ فَقَالَ أَرَأَيْتَ الإِبِلَ تَكُونُ فِي الرِّمَالِ أَمْثَالَ الظِّبَاءِ فَيَأْتِيهِ الْبَعِيرُ الأَجْرَبُ فَتَجْرَبُ‏.‏ قَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ فَمَنْ أَعْدَى الأَوَّلَ ‏"‏‏.‏
