It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: Those people who gather in a place for a meeting but do not remember Allah in it and then get up and leave, it will be a cause of regret for them on the Day of Resurrection.
