وقيل لمحمد بن علي عليهما السلام: ما لموت؟ قال: هو النوم الذي يأتيكم كل ليلة إلا أنه طويل مدته لا ينتبه منه إلا يوم القيامة، فمن رأى في نومه من أصناف الفرح مالا يقادر قدره ومن أصناف الأهوال مالا يقادر قدره؟ فكيف حال فرح في النوم ووجل فيه؟ هذا هو الموت فاستعدوا له.
5.	It was said to Muhammed bin Ali, peace be upon them both: What is death? He said: It is the sleep that comes to you every night, except that its duration is long and one will not notice it except on the Day of Resurrection. Who has seen in his sleep from the types of happiness what he cannot evaluate its value, and from the types of horrors what he cannot evaluate its value? How is the case of happiness and dread during sleep? That is death, so prepare for it.
