Mishkat al-Masabih 2278

Abu Sa'id said that Mu'awiya went out to a circle in the mosque and asked them what had made them sit together. When they replied that they had sat down to remember God, he said, "I adjure you by God, has nothing else made you sit together?" On their reply that there was certainly no other cause he said, "I did not adjure you because I suspected you. No one in my position with relation to God’s messenger has fewer traditions from him than I have; but God’s messenger went out to a circle of his companions and asked them what had made them sit there, and when they replied that they had sat together to remember God and praise Him for guiding them to Islam and bestowing favour on them he said, ‘I adjure you by God, has nothing else made you sit together?’ On their replying that there was certainly no other cause he said, ‘I did not adjure you because’ I suspected you, but Gabriel came to me and told me God is speaking proudly of you to the angels’." Muslim transmitted it.
