"Whoever sits in a place and does not remember Allah there, that place will be a cause of loss (anxiety and distress) for him from Allah; and whoever lies down in a place where he does not remember Allah, that place will be a cause of loss (anxiety and distress) for him from Allah." [ حسن، سنن ابي داؤد:4856 وعنده: ”لايذكر“ السنن الكبريٰ للنسائي:237/1]
