Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah said, "If anyone sits in a gathering where he does not remember Allah, he will bring grief upon himself (on the Day of Resurrection), and he who lies down in a place where he does not remember Allah, will bring grief upon himself (on the Day of Resurrection)."[Abu Dawud].
