Umar bin al-Khattab ؓ told me: he heard the Prophet ﷺ ʿA rider will travel through the streets of Madinah, then he will say: There used to be many believers here.ʿ  

سَمِعْتُ النَّبِيَّ ﷺ يَقُولُ لَيَسِيرَنَّ الرَّاكِبُ فِي جَنَبَاتِ الْمَدِينَةِ ثُمَّ لَيَقُولُ لَقَدْ كَانَ فِي هَذَا حَاضِرٌ مِنَ الْمُؤْمِنِينَ كَثِيرٌ قَالَ أَبِي أَحْمَدُ بْنُ حَنْبَلٍ وَلَمْ يَجُزْ بِهِ حَسَنٌ الْأَشْيَبُ جَابِرًا  

[Machine] The Prophet Muhammad ﷺ said, "If a person is riding along the side of the Medina valley, they should say, 'Indeed, there were many believers present here at one time.'"  

أَنَّ رَسُولَ اللهِ ﷺ قَالَ لَيَسِيرَنَّ رَاكِبٌ فِي جَنْبِ وَادِي الْمَدِينَةِ فَلَيَقُولَنَّ لَقَدْ كَانَ فِي هَذِهِ مَرَّةً حَاضِرَةٌ مِنَ الْمُؤْمِنِينَ كَثِيرٌ  

[Machine] The Prophet ﷺ said, "It will not be long before a rider will travel towards Medina." Qutaybah said, "On the outskirts of Medina, he should say, 'Indeed, there used to be many believers present here during this time.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ لَيَسِيرَنَّ رَاكِبٌ فِي جِهَةِ الْمَدِينَةِ قَالَ قُتَيْبَةُ فِي جَانِبِ الْمَدِينَةِ فَلَيَقُولَنَّ لَقَدْ كَانَ فِي هَذِهِ مَرَّةً حَاضِرٌ مِنَ الْمُؤْمِنِينَ كَثِيرٌ
