Maalik Ibn Deenaar said: “By Allaah! If it was possible for me not to sleep, I would not sleep out of fear that the punishment would descend and I am asleep. By Allaah! If I had some helpers, I would spread them out among the dunyaa and give them orders to cry out to the people, ‘O mankind! The Fire! The Fire!’ “ [Al-Ihyaa, 4/567]
