Virtues and Merits of the Prophet (pbuh) and his Companions
حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا الْوَلِيدُ، قَالَ حَدَّثَنِي ابْنُ جَابِرٍ، قَالَ حَدَّثَنِي عُمَيْرُ بْنُ هَانِئٍ، أَنَّهُ سَمِعَ مُعَاوِيَةَ، يَقُولُ سَمِعْتُ النَّبِيَّ صلى الله عليه وسلم يَقُولُ " لاَ يَزَالُ مِنْ أُمَّتِي أُمَّةٌ قَائِمَةٌ بِأَمْرِ اللَّهِ، لاَ يَضُرُّهُمْ مَنْ خَذَلَهُمْ وَلاَ مَنْ خَالَفَهُمْ حَتَّى يَأْتِيَهُمْ أَمْرُ اللَّهِ وَهُمْ عَلَى ذَلِكَ ". قَالَ عُمَيْرٌ فَقَالَ مَالِكُ بْنُ يُخَامِرَ قَالَ مُعَاذٌ وَهُمْ بِالشَّأْمِ. فَقَالَ مُعَاوِيَةُ هَذَا مَالِكٌ يَزْعُمُ أَنَّهُ سَمِعَ مُعَاذًا يَقُولُ وَهُمْ بِالشَّامِ.Narrated Muawiya:I heard the Prophet (ﷺ) saying, "A group of people amongst my followers will remain obedient to Allah's orders and they will not be harmed by anyone who will not help them or who will oppose them, till Allah's Order (the Last Day) comes upon them while they are still on the right path
