[Machine] "A group of people came to the city with the Prophet ﷺ, and there was a disease in it. So the Prophet ﷺ forbade them from leaving until he gave them permission. But they left without his permission, so the Messenger of Allah ﷺ said, 'Indeed, the city is like a sieve that filters out impurities, just as a sieve filters out impurities from iron.'"
أَنَّ قَوْمًا قَدِمُوا الْمَدِينَةَ مَعَ النَّبِيِّ ﷺ وَبِهَا مَرَضٌ فَنَهَاهُمُ النَّبِيُّ ﷺ أَنْ يَخْرُجُوا حَتَّى يَأْذَنَ لَهُمْ فَخَرَجُوا بِغَيْرِ إِذْنِهِ فَقَالَ رَسُولُ اللهِ ﷺ إِنَّمَا الْمَدِينَةُ كَالْكِيرِ تَنْفِي الْخَبَثَ كَمَا يَنْفِي الْكِيرُ خَبَثَ الْحَدِيدِ
