وعن عائشة رضي الله عنها، قالت‏:‏ كان النبي صلى الله عليه وسلم ، يقوم من الليل حتى تتفطر قدماه، فقلت له‏:‏ لم تصنع هذا يا رسول الله، وقد غفر لك ما تقدم من ذنبك وما تأخر‏؟‏ قال‏:‏ ‏"‏أفلا أكون عبدًا شكورًا‏"‏‏.‏ ‏(‏‏(‏متفق عليه وعن المغيرة بن شعبة نحوه، متفق عليه‏)‏‏)‏‏.‏

Abu Hurairah (May Allah be pleased with him) reported

The Messenger of Allah (ﷺ) said, "When any one of you sleeps, Satan ties three knots at the back of his neck. He recites this incantation at every knot: 'You have a long night, so sleep.' If he awakes and remembers Allah, one knot is loosened. If he performs Wudu', the (second) knot is loosened; and if he performs prayer, (all) knots are loosened. He begins his morning in a happy and refreshed mood; otherwise, he gets up in bad spirits and sluggish state."[Al-Bukhari and Muslim].
