[Machine] I heard Abu Tha'labah al-Khushani, the companion of the Messenger of Allah ﷺ, say that he heard him saying while he was in Fustat during the caliphate of Mu'awiyah. Mu'awiyah was the richest person in Constantinople. He said, "By Allah, this nation will not be defeated in half a day when you see the banquet of a man and his household in Syria. At that moment, Constantinople will be conquered."  

سَمِعْتُ أَبَا ثَعْلَبَةَ الْخُشَنِيَّ صَاحِبَ رَسُولِ اللهِ ﷺ أَنَّهُ سَمِعَهُ يَقُولُ وَهُوَ بِالْفُسْطَاطِ فِي خِلَافَةِ مُعَاوِيَةَ وَكَانَ مُعَاوِيَةُ أَغْزَى النَّاسَ الْقُسْطَنْطِينِيَّةَ فَقَالَ وَاللهِ لَا تَعْجِزُ هَذِهِ الْأُمَّةُ مِنْ نِصْفِيَوْمٍ إِذَا رَأَيْتَ الشَّامَ مَائِدَةَ رَجُلٍ وَاحِدٍ وَأَهْلِ بَيْتِهِ فَعِنْدَ ذَلِكَ فَتْحُ الْقُسْطَنْطِينِيَّةِ
