What is meant by sleeping and what is it true? Sleep as mentioned in the dictionary : a period of rest for the body and mind, during which the will and awareness are partially or totally absent, and during which the physical functions partially cease . And it is said to many who sleep : Noaman, and : Sleep . Sleep is called : sleep; And so it is said : He saw such-and-such in his dream, that is, in his sleep. The Almighty said [ Oh, son, I see in a dream that I slaughter you, so see what you see …] and what I see in a dream : that is, in sleep . Sleeping is one of the characteristics of human beings, and that is why God himself relieved it by saying : [It does not take a year nor sleep ] , and the Sunnah is sleepiness, and for this he said : There is no sleep, and sleep is stronger than the Sunnah, and it came in the Sahih on the authority of Abu Musa Al-Ash’ari who said : The Messenger of God rose up in us May God bless him and grant him peace, and he said : [ God does not sleep and he should not sleep ]. In this sense, God Almighty says: [ He is the one who made the night wear for you . And sleep is slumber . And he made the day a nashr ] , and the meaning : that he made sleep interrupt the movement; For the rest of the body, then the night is still in motion, and the movements rest and rest, so that the soul and body sleep comfortably .
