Abdullah ibn Mas’ud reported: The Prophet, peace and blessings be upon him, said, “You are exposed to fire, you are exposed to fire! If you perform the dawn prayer, it will cleanse you. Then, you are exposed to fire, you are exposed to fire! If you perform the noon prayer, it will cleanse you. Then, you are exposed to fire, you are exposed to fire! If you pray the mid-day prayer, it will cleanse you. Then, you are exposed to fire, you are exposed to fire! If you pray the sunset prayer, it will cleanse you. Then, you are exposed to fire, you are exposed to fire! If you pray the evening prayer, it will cleanse you. Then, when you sleep, nothing will be written against you until you wake up.”

عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ عَنِ النَّبِيِّ صَلَّى اللهُ عَلَيْهِ وَسَلَّمَ قَالَ تَحْتَرِقُونَ تَحْتَرِقُونَ فَإِذَا صَلَّيْتُمُ الْفَجْرَ غَسَلَتْهَا ثُمَّ تَحْتَرِقُونَ تَحْتَرِقُونَ فَإِذَا صَلَّيْتُمُ الظُّهْرَ غَسَلَتْهَا ثُمَّ تَحْتَرِقُونَ تَحْتَرِقُونَ فَإِذَا صَلَّيْتُمُ الْعَصْرَ غَسَلَتْهَا ثُمَّ تَحْتَرِقُونَ تَحْتَرِقُونَ فَإِذَا صَلَّيْتُمُ الْمَغْرِبَ غَسَلَتْهَا ثُمَّ تَحْتَرِقُونَ تَحْتَرِقُونَ فَإِذَا صَلَّيْتُمُ الْعِشَاءَ غَسَلَتْهَا ثُمَّ تَنَامُونَ فَلَا يُكْتَبُ عَلَيْكُمْ شَيْءٌ حَتَّى تَسْتَيْقِظُونَ
