Sahih Muslim 2700 a, b

Agharr Abi Muslim reported:

I bear witness to the fact that both Abu Huraira and Abu Sa'id Khudri were present when Allah's Messenger may peace be upon him) said: The people do not sit but they are surrounded by angels and covered by Mercy, and there descends upon them tranquillity as they remember Allah, and Allah makes a mention of them to those who are near Him. This hadith has been narrated on the authority of Shu'ba with the same chain of transmitters.
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، سَمِعْتُ أَبَا إِسْحَاقَ، يُحَدِّثُ عَنِ الأَغَرِّ أَبِي مُسْلِمٍ، أَنَّهُ قَالَ أَشْهَدُ عَلَى أَبِي هُرَيْرَةَ وَأَبِي سَعِيدٍ الْخُدْرِيِّ أَنَّهُمَا شَهِدَا عَلَى النَّبِيِّ صلى الله عليه وسلم أَنَّهُ قَالَ ‏ "‏ لاَ يَقْعُدُ قَوْمٌ يَذْكُرُونَ اللَّهَ عَزَّ وَجَلَّ إِلاَّ حَفَّتْهُمُ الْمَلاَئِكَةُ وَغَشِيَتْهُمُ الرَّحْمَةُ وَنَزَلَتْ عَلَيْهِمُ السَّكِينَةُ وَذَكَرَهُمُ اللَّهُ فِيمَنْ عِنْدَهُ ‏"‏ ‏.‏

وَحَدَّثَنِيهِ زُهَيْرُ بْنُ حَرْبٍ، حَدَّثَنَا عَبْدُ الرَّحْمَنِ، حَدَّثَنَا شُعْبَةُ، فِي هَذَا الإِسْنَادِ نَحْوَهُ ‏.‏
