[Machine] "When the Prophet ﷺ mentioned the Hour, his anger would intensify, his voice would become louder, and his cheeks would turn red as if he were a warner of an army that had attacked in the morning and reached you in the evening. Ali ibn Abadan narrated to us, Ahmad ibn Ubayd al-Saffar narrated to us, Ismail al-Qadi narrated to us, Muhammad ibn Kathir narrated to us, Sufyan mentioned it briefly."  

البيهقي:٥٧٥٥وَرَوَاهُ سُفْيَانُ الثَّوْرِيُّ عَنْ جَعْفَرٍ بِإِسْنَادِهِ فَقَالَ

كَانَ رَسُولُ اللهِ ﷺ إِذَا ذَكَرَ السَّاعَةَ اشْتَدَّ غَضَبُهُ وَارْتَفَعَ صَوْتُهُ وَاحْمَرَّتْ وَجْنَتَاهُ كَأَنَّهُ نَذِيرُ جَيْشٍ صَبَّحَتْكُمْ مَسَّتْكُمْ أَخْبَرَنَا عَلِيُّ بْنُ عَبْدَانَ ثنا أَحْمَدُ بْنُ عُبَيْدٍ الصَّفَّارُ ثنا إِسْمَاعِيلُ الْقَاضِي ثنا مُحَمَّدُ بْنُ كَثِيرٍ ثنا سُفْيَانُ فَذَكَرَهُ مُخْتَصَرًا
