قَالَ أَبُو سَلَمَةَ بْنُ عَبْدِ الرَّحْمَنِ: سَمِعْتُ أَبَا هُرَيْرَةَ، عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ، قَالَ: "لَا تُورِدُوا الْمُمْرِضَ عَلَى الْمُصِحِّ".
صحیح بخاری · Hadith 5775
Abu Huraira also said: Allah's Apostle 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 said, "Then who conveyed the (mange) disease to the first camel?"
