[Machine] The Messenger of Allah ﷺ said, "There is no contagious disease except with the permission of Allah and His Messenger." It has been reported to us that the Messenger of Allah ﷺ had protected against plague, and Umar had protected against smallpox and scrofula.  

قَالَ رَسُولُ اللهِ ﷺ لَا حِمَى إِلَّا لِلَّهِ وَرَسُولِهِ قَالَ وَبَلَغَنَا أَنَّ رَسُولَ اللهِ ﷺ حَمَى النَّقِيعَ وَأَنَّ عُمَرَ حَمَى الشُّرَفَ وَالرَّبَذَةَ
