"‏ يَا أَنَسُ إِنَّ النَّاسَ يُمَصِّرُونَ أَمْصَارًا وَإِنَّ مِصْرًا مِنْهَا يُقَالُ لَهُ الْبَصْرَةُ أَوِ الْبُصَيْرَةُ فَإِنْ أَنْتَ مَرَرْتَ بِهَا أَوْ دَخَلْتَهَا فَإِيَّاكَ وَسِبَاخَهَا وَكِلاَءَهَا وَسُوقَهَا وَبَابَ أُمَرَائِهَا وَعَلَيْكَ بِضَوَاحِيهَا فَإِنَّهُ يَكُونُ بِهَا خَسْفٌ وَقَذْفٌ وَرَجْفٌ وَقَوْمٌ يَبِيتُونَ يُصْبِحُونَ قِرَدَةً وَخَنَازِيرَ ‏"

The Prophet (ﷺ) said: The people will establish cities, Anas, and one of them will be called al-Basrah or al-Busayrah. If you should pass by it or enter it, avoid its salt-marshes, its Kall, its market, and the gate of its commanders, and keep to its environs, for the earth will swallow some people up, pelting rain will fall and earthquakes will take place in it, and there will be people who will spend the night in it and become apes and swine in the morning.
