It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that once Sayyiduna Mu'awiyah (may Allah be pleased with him) came to a gathering of remembrance in the mosque and asked them, "What has made you sit here?" They replied, "We are sitting here remembering Allah." Sayyiduna Mu'awiyah (may Allah be pleased with him) asked them under oath, "Is it really only this that has made you sit here?" They swore and replied, "We are sitting here only for this purpose." Sayyiduna Mu'awiyah (may Allah be pleased with him) said, "I did not make you swear because I thought you were lying. There will be no one who narrates fewer Prophetic traditions than me. The fact is that once the Prophet (peace and blessings be upon him) also came to a gathering of his companions and asked them the same questions and made them swear, and then said, 'I did not make you swear because I thought you were lying, but rather Jibreel (peace be upon him) came to me and informed me that at this moment Allah is boasting about you to His angels.'"
