It is narrated from Sayyiduna Abu Sa'id al-Khudri (may Allah be pleased with him) that Sayyiduna Mu'awiyah (may Allah be pleased with him) came to a circle (of people) in the mosque and asked: "What has made you sit here?" They said: "We are sitting to remember Allah, the Mighty and Majestic." He asked: "By Allah, has nothing but this made you sit?" They replied: "By Allah, nothing but this purpose has made us sit." Then Sayyiduna Mu'awiyah (may Allah be pleased with him) said: "Know that the Messenger of Allah (peace and blessings be upon him) came to a circle of his Companions and asked: 'What has made you sit here?' They said: 'We are sitting to remember Allah, the Mighty and Majestic, and to praise Him for guiding us to Islam and bestowing this great favour upon us.' He (peace and blessings be upon him) asked: 'By Allah, has nothing but this made you sit?' They said: 'By Allah, nothing but this purpose has made us sit.' He (peace and blessings be upon him) said: 'Listen! I did not make you swear out of any suspicion of you; rather, Jibril (peace be upon him) came to me and informed me that Allah Almighty is boasting about you to the angels.'"
