An excellent awakening

Sayyiduna Abu Hurairah Radhiyallahu Anhu narrates that Rasulullah Sallallahu Alayhi wa Sallam said, “When any one of you goes to sleep, Shaytaan ties three knots at the back of his neck, sealing each knot with the following words, " You have a long night, so sleep." So if a person wakes up and remembers Allah, one knot will be loosened. If he performs ablution, two knots are loosened. And if he performs Salah, all three knots will be loosened. In the morning he will be energetic and in good spirits; otherwise he wakes up in a bad mood and lethargic.” (Muslim)
