It was narrated that Abu Sa'eed Al-Khudri said:"Mu'awiyah, (may Allah be pleased with him,) said: 'The Messenger of Allah [SAW] went out to a circle - meaning, of his Companions - and said: 'What are you doing?' They said: 'We have come together to pray to Allah and praise Him for guiding us to His religion, and blessing us with you.' He said: 'I ask you, by Allah, is that the only reason?' They said: 'By Allah, we have not come together for any other reason.' He said: 'I am not asking you to swear to an oath because of any suspicion; rather Jibril came to me and told me that Allah, the Mighty and Sublime, is boasting of you to the angels.'"
أَخْبَرَنَا سَوَّارُ بْنُ عَبْدِ اللَّهِ، قَالَ حَدَّثَنَا مَرْحُومُ بْنُ عَبْدِ الْعَزِيزِ، عَنْ أَبِي نَعَامَةَ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، عَنْ أَبِي سَعِيدٍ الْخُدْرِيِّ، قَالَ قَالَ مُعَاوِيَةُ رَضِيَ اللَّهُ عَنْهُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَرَجَ عَلَى حَلْقَةٍ - يَعْنِي مِنْ أَصْحَابِهِ - فَقَالَ " مَا أَجْلَسَكُمْ " . قَالُوا جَلَسْنَا نَدْعُو اللَّهَ وَنَحْمَدُهُ عَلَى مَا هَدَانَا لِدِينِهِ وَمَنَّ عَلَيْنَا بِكَ . قَالَ " آللَّهِ مَا أَجْلَسَكُمْ إِلاَّ ذَلِكَ " . قَالُوا آللَّهِ مَا أَجْلَسَنَا إِلاَّ ذَلِكَ . قَالَ " أَمَا إِنِّي لَمْ أَسْتَحْلِفْكُمْ تُهَمَةً لَكُمْ وَإِنَّمَا أَتَانِي جِبْرِيلُ عَلَيْهِ السَّلاَمُ فَأَخْبَرَنِي أَنَّ اللَّهَ عَزَّ وَجَلَّ يُبَاهِي بِكُمُ الْمَلاَئِكَةَ " .
