Mu’awiyah reported: The Messenger of Allah, peace and blessings be upon him, came out to a gathering of his Companions, saying, “Why are you sitting?” They said, “We are sitting to remember Allah, to praise him for guiding us to Islam and for blessing us with it.” The Prophet said, “Are you only sitting like this for the sake of Allah?” They said, “By Allah, we are only sitting for this reason.” The Prophet said, “Surely, I would not ask for your oath because I doubt you, but rather Gabriel has told me that Allah Almighty is boasting of you before the angels.”

عَنْ مُعَاوِيَةَ قال إِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ خَرَجَ عَلَى حَلْقَةٍ مِنْ أَصْحَابِهِ فَقَالَ مَا أَجْلَسَكُمْ قَالُوا جَلَسْنَا نَذْكُرُ اللَّهَ وَنَحْمَدُهُ عَلَى مَا هَدَانَا لِلْإِسْلَامِ وَمَنَّ بِهِ عَلَيْنَا قَالَ آللَّهِ مَا أَجْلَسَكُمْ إِلَّا ذَاكَ قَالُوا وَاللَّهِ مَا أَجْلَسَنَا إِلَّا ذَاكَ قَالَ أَمَا إِنِّي لَمْ أَسْتَحْلِفْكُمْ تُهْمَةً لَكُمْ وَلَكِنَّهُ أَتَانِي جِبْرِيلُ فَأَخْبَرَنِي أَنَّ اللَّهَ عَزَّ وَجَلَّ يُبَاهِي بِكُمْ الْمَلَائِكَةَ
