Messenger of Allah ﷺ said, 'There is no 'Adwa (no disease is conveyed from the sick to the healthy without Allah's permission), nor Safar, nor Hama." 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 mangy." The Prophet ﷺ said, "Then who conveyed the (mange) disease to the first one?"  

إِنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ عَدْوَى وَلاَ صَفَرَ وَلاَ هَامَةَ فَقَالَ أَعْرَابِيٌّ يَا رَسُولَ اللَّهِ فَمَا بَالُ إِبِلِي تَكُونُ فِي الرَّمْلِ كَأَنَّهَا الظِّبَاءُ فَيَأْتِي الْبَعِيرُ الأَجْرَبُ فَيَدْخُلُ بَيْنَهَا فَيُجْرِبُهَا فَقَالَ فَمَنْ أَعْدَى الأَوَّلَ رَوَاهُ الزُّهْرِيُّ عَنْ أَبِي سَلَمَةَ وَسِنَانِ بْنِ أَبِي سِنَانٍ  

The Prophet ﷺ said, 'No 'Adwa (i.e. no contagious disease is conveyed to others without Allah's permission); nor (any evil omen in the month of) Safar; nor Hama" A bedouin said, "O Messenger of Allah ﷺ! What about the camels which, when on the sand (desert) look like deers, but when a mangy camel mixes with them they all get infected with mange?" On that Allah s Apostle said, "Then who conveyed the (mange) disease to the first (mangy) camel?"  

قَالَ النَّبِيُّ ﷺ لاَ عَدْوَى وَلاَ صَفَرَ وَلاَ هَامَةَ فَقَالَ أَعْرَابِيٌّ يَا رَسُولَ اللَّهِ فَمَا بَالُ الإِبِلِ تَكُونُ فِي الرَّمْلِ كَأَنَّهَا الظِّبَاءُ فَيُخَالِطُهَا الْبَعِيرُ الأَجْرَبُ فَيُجْرِبُهَا فَقَالَ رَسُولُ اللَّهِ ﷺ فَمَنْ أَعْدَى الأَوَّلَ  

There is no infection, no safar, no hama. A desert Arab said: Messenger of Allah, how is it that when the camel is in the sand it is like a deer-then a camel afflicted with scab mixes with it and it is affected by sub? He (the Holy Prophet) said: Who infected the first one? Note: The majority of scholars interpret this to mean that these things in and of themselves do not transmit or cause harm through supernatural or hidden means but that Allah is ultimately in control and any fearful superstition around these is false.  

قَالَ رَسُولُ اللَّهِ ﷺ لاَ عَدْوَى وَلاَ صَفَرَ وَلاَ هَامَةَ فَقَالَ أَعْرَابِيٌّ يَا رَسُولَ اللَّهِ فَمَا بَالُ الإِبِلِ تَكُونُ فِي الرَّمْلِ كَأَنَّهَا الظِّبَاءُ فَيَجِيءُ الْبَعِيرُ الأَجْرَبُ فَيَدْخُلُ فِيهَا فَيُجْرِبُهَا كُلَّهَا قَالَ فَمَنْ أَعْدَى الأَوَّلَ

قَالَ رَسُولُ اللهِ ﷺ لَا عَدْوَى وَلَا صَفَرَ وَلَا هَامَةَ قَالَ أَعْرَابِيٌّ فَمَا بَالُ الْإِبِلِ تَكُونُ فِي الرَّمْلِ كَأَنَّهَا الظِّبَاءُ فَيُخَالِطُهَا الْبَعِيرُ الْأَجْرَبُ فَيُجْرِبُهَا؟ فَقَالَ النَّبِيُّ ﷺ فَمَنْ كَانَ أَعْدَى الْأَوَّلَ؟

(Using translation from Muslim 2220a)
