[Machine] I heard the Messenger of Allah ﷺ saying, "Constantinople will be conquered, and what a wonderful leader its leader will be, and what a wonderful army that army will be." Ubaidullah said: "Then Maslamah ibn Abd al-Malik called me and asked me about this hadith, so I narrated it to him, and he (Maslamah ibn Abd al-Malik) then conquered Constantinople."
سَمِعْتُ رَسُولَ اللَّهِ ﷺ يَقُولُ «لَتُفْتَحَنَّ الْقُسْطَنْطِينِيَّةُ وَلَنِعْمَ الْأَمِيرُ أَمِيرُهَا وَلَنِعْمَ الْجَيْشُ ذَلِكَ الْجَيْشُ» قَالَ عُبَيْدُ اللَّهِ «فَدَعَانِي مَسْلَمَةُ بْنُ عَبْدِ الْمَلِكِ فَسَأَلَنِي عَنْ هَذَا الْحَدِيثِ فَحَدَّثْتُهُ فَغَزَا الْقُسْطَنْطِينِيَّةَ»
