The Messenger of Allah ﷺ said: Some of my people will alight on low-lying ground, which they will call al-Basrah, beside a river called the Tigris over which there is a bridge. Its people will be numerous and it will be one of the capital cities of immigrants (or one of the capital cities of Muslims, according to the version of Ibn Yahya who reported from Abu Ma'mar). At the end of time the descendants of Qantura' will come with broad faces and small eyes and alight on the bank of the river. The town's inhabitants will then separate into three sections, one of which will follow cattle and (live in) the desert and perish, another of which will seek security for themselves and perish, but a third will put their children behind their backs and fight the invaders, and they will be the martyrs.
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ يَنْزِلُ نَاسٌ مِنْ أُمَّتِي بِغَائِطٍ يُسَمُّونَهُ الْبَصْرَةَ عِنْدَ نَهْرٍ يُقَالُ لَهُ دِجْلَةُ يَكُونُ عَلَيْهِ جِسْرٌ يَكْثُرُ أَهْلُهَا وَتَكُونُ مِنْ أَمْصَارِ الْمُهَاجِرِينَ قَالَ ابْنُ يَحْيَى قَالَ أَبُو مَعْمَرٍ وَتَكُونُ مِنْ أَمْصَارِ الْمُسْلِمِينَ فَإِذَا كَانَ فِي آخِرِ الزَّمَانِ جَاءَ بَنُو قَنْطُورَاءَ عِرَاضُ الْوُجُوهِ صِغَارُ الأَعْيُنِ حَتَّى يَنْزِلُوا عَلَى شَطِّ النَّهْرِ فَيَتَفَرَّقُ أَهْلُهَا ثَلاَثَ فِرَقٍ فِرْقَةٌ يَأْخُذُونَ أَذْنَابَ الْبَقَرِ وَالْبَرِّيَّةِ وَهَلَكُوا وَفِرْقَةٌ يَأْخُذُونَ لأَنْفُسِهِمْ وَكَفَرُوا وَفِرْقَةٌ يَجْعَلُونَ ذَرَارِيَّهُمْ خَلْفَ ظُهُورِهِمْ وَيُقَاتِلُونَهُمْ وَهُمُ الشُّهَدَاءُ
