«تَطْلُعُ عَلَيْكُمْ عِنْدَ السَّاعَةِ سَحَابَةٌ سَوْدَاءُ مِنَ الْمَغْرِبِ مِثْلَ التُّرْسِ، فَمَا تَزَالُ تَرْتَفِعُ فِي السَّمَاءِ ثُمَّ يُنَادِي مُنَادٍ فِيهَا: يَا أَيُّهَاالنَّاسُ فَيُقْبِلُ النَّاسُ بَعْضُهُمْ عَلَى بَعْضٍ: هَلْ سَمِعْتُمْ، فَمِنْهُمْ مَنْ يَقُولُ: نَعَمْ، وَمِنْهُمْ مَنْ يَشُكُّ، ثُمَّ يُنَادِي الثَّانِيَةَ: يَا أَيُّهَا النَّاسُ فَيَقُولُ النَّاسُ بَعْضُهُمْ لِبَعْضٍ: هَلْ سَمِعْتُمْ، فَيَقُولُونَ: نَعَمْ، ثُمَّ يُنَادِي الثَّالِثَةَ: يَا أَيُّهَا النَّاسُ أَتَى أَمْرُ اللهِ فَلَا تَسْتَعْجِلُوه»
