ذِكْرُ نَفْيِ الْمَدِينَةِ عَنْ نَفْسِهَا الْخَبَثَ مِنَ الرِّجَالِ كَالْكِيرِ
[Machine] "That a Bedouin pledged allegiance to the Messenger of Allah ﷺ on Islam and then the Bedouin became sick in the city. So, the Bedouin left and the Messenger of Allah ﷺ said, 'Indeed, the city is like a fever that expels its impurities and leaves behind what is pure.'"
أَنَّ أَعْرَابِيًّا بَايَعَ رَسُولَ اللَّهِ ﷺ عَلَى الْإِسْلَامِ فَأَصَابَ الْأَعْرَابِيَّ وَعْكٌ بِالْمَدِينَةِ فَخَرَجَ الْأَعْرَابِيُّ فَقَالَ رَسُولُ اللَّهِ ﷺ «إِنَّمَا الْمَدِينَةُ كَالْكِيرِ تَنْفِي خَبَثَهَا وَيَنْصَعُ طَيِّبُهَا»
