"The Prophet (SAW) went out to the circle of his companions and said, 'What makes you sit here?' They said, 'We are sitting here in order to remember Allah and to praise Him for He guided us to the path of Islam and conferred favours upon us.'
Thereupon he [the Prophet SAW] swore by Allah and asked if that was the only purpose of their sitting here. They said, 'By Allah, we are only sitting here for that very purpose;' whereupon he said, 'I am not asking you to take an oath because of any allegation against you, but because Gabriel came to me and informed me that Allah, the Exalted and Glorious, was talking to the angels about your magnificence." (Sahih Muslim in Kitab Az-Zikr, No 2701/40)
Personal Comment: This action is both easy, enjoyable and healthy. The act of assembing for the purpose of speaking about Allah, His Attributes, His Qualities, His Perfection, His Justice etc. This can also include speaking about how we were before we became good Muslims, what we were like and how we think, behave and act differently now. This can further include speaking about Jannah and what is there and also speaking abot the Prophet and good Muslims and how Allah has guided us through each of them.
