حَدَّثَنَا عَبْدُ الْمَلِكِ بْنُ شُعَيْبِ بْنِ اللَّيْثِ حَدَّثَنِى عَبْدُ اللَّهِ بْنُ وَهْبٍ أَخْبَرَنِى اللَّيْثُ بْنُ سَعْدٍ حَدَّثَنِى مُوسَى بْنُ عُلَىٍّ عَنْ أَبِيهِ قَالَ قَالَ الْمُسْتَوْرِدُ الْقُرَشِىُّ عِنْدَ عَمْرِو بْنِ الْعَاصِ سَمِعْتُ رَسُولَ اللَّهِ -صلى الله عليه وسلم- يَقُولُ « تَقُومُ السَّاعَةُ وَالرُّومُ أَكْثَرُ النَّاسِ ». فَقَالَ لَهُ عَمْرٌو أَبْصِرْ مَا تَقُولُ. قَالَ أَقُولُ مَا سَمِعْتُ مِنْ رَسُولِ اللَّهِ -صلى الله عليه وسلم- قَالَ لَئِنْ قُلْتَ ذَلِكَ إِنَّ فِيهِمْ لَخِصَالاً أَرْبَعًا إِنَّهُمْ لأَحْلَمُ النَّاسِ عِنْدَ فِتْنَةٍ وَأَسْرَعُهُمْ إِفَاقَةً بَعْدَ مُصِيبَةٍ وَأَوْشَكُهُمْ كَرَّةً بَعْدَ فَرَّةٍ وَخَيْرُهُمْ لِمِسْكِينٍ وَيَتِيمٍ وَضَعِيفٍ وَخَامِسَةٌ حَسَنَةٌ جَمِيلَةٌ وَأَمْنَعُهُمْ مِنْ ظُلْمِ الْمُلُوكِ.

Musa bin 'Ulayy narrated that his father said: In the presence of 'Amr bin Al-'As, Al-Mustawrid Al-Qurashi said: I heard the Messenger of Allah (s.a.w) say: "The Hour will begin when the Byzantines are the most prevalent of people." 'And said to him: Watch what you are saying. He said: I say that which I heard from the Messenger of Allah (s.a.w). He said: As you say that, indeed they have four qualities: They are the most patient of people at times of tribulation; they are the quickest to recover after a calamity; they are the quickest to regroup and attack after a defeat; and they are the best of them to the poor, orphans and weak. And a fifth good quality is that they are most resistant of the oppression of kings.
