the root of 'subat' is from stretching. It is said: a woman 'sabatat' her hair, meaning: she unbraided it and let it loose, and a man is 'masbut', meaning: stretched of stature. It is said: sleep is called 'subat' because it occurs with stretching, and in stretching there is a sense of rest. It is also said: 'al-sabt' is cutting off; thus, sleep is a cessation from occupation, and from this is the 'Sabt' (Sabbath) of the Jews, because of their cessation from work during it.
