"There is no contagion, no hama and no serpent in a hungry belly. However, the possessor of sick livestock must not stop at the same place as the possessor of healthy livestock, but the possessor of healthy livestock may stop wherever he wishes." They said, "Messenger of Allah, Why is that?" The Messenger of Allah ﷺ said, "It is harmful."  

أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ لاَ عَدْوَى وَلاَ هَامَ وَلاَ صَفَرَ وَلاَ يَحُلَّ الْمُمْرِضُ عَلَى الْمُصِحِّ وَلْيَحْلُلِ الْمُصِحُّ حَيْثُ شَاءَ فَقَالُوا يَا رَسُولَ اللَّهِ وَمَا ذَاكَ فَقَالَ رَسُولُ اللَّهِ ﷺ إِنَّهُ أَذًى  

[Machine] The Messenger of Allah ﷺ said, "There is no contagious disease and the sick should not visit the healthy. The healthy should visit the sick wherever they wish." It was said, "What is the reason for this, O Messenger of Allah?" He said, "It is harm."  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَا عَدْوَى وَلَا يَحِلُّ الْمُمْرِضُ عَلَى الْمُصِحِّ وَلْيَحِلَّ الْمُصِحُّ حَيْثُ شَاءَ قِيلَ مَا بَالُ ذَلِكَ يَا رَسُولَ اللهِ؟ قَالَ إِنَّهُ أَذًى  

"لا عَدْوَى، وَلا هَامَةَ، وَلا صَفَرَ، وَلا يَحِل المُمْرِضُ عَلَى المُصِحِّ وَليَحِلَّ المُصحُّ حَيثُ شَاءَ، قيل: وَلِمَ ذَاكَ؟ قال: لأنَّهُ أَذى".
