SHAFAQNA – It is narrated from Imam Ali (AS) who said: The body has six conditions: Health, illness, death, life, sleep, wakefulness. The soul is also the same: The life of the soul is its knowledge; and ignorance is its death, doubt its illness, certainty its health, sleep its negligence, and wakefulness is its awareness [1].
