What a Person Should Say When They Lie Down to Sleep
Man Lā Yaḥḍuruh al-Faqīh|Volume 1|Book 1|Chapter 64
وَ رَوَى بَكْرُ بْنُ مُحَمَّدٍ عَنْهُ عَلَيْهِ اَلسَّلاَمُ أَنَّهُ قَالَ: «مَنْ قَالَ حِينَ يَأْخُذُ مَضْجَعَهُ ثَلاَثَ مَرَّاتٍ: اَلْحَمْدُ لِلَّهِ اَلَّذِي عَلاَ فَقَهَرَ وَ اَلْحَمْدُ لِلَّهِ اَلَّذِي بَطَنَ فَخَبَرَ وَ اَلْحَمْدُ لِلَّهِ اَلَّذِي مَلَكَ فَقَدَرَ وَ اَلْحَمْدُ لِلَّهِ اَلَّذِي «يُحْيِ اَلْمَوْتىٰ» وَ يُمِيتُ اَلْأَحْيَاءَ «وَ هُوَ عَلىٰ كُلِّ شَيْءٍ قَدِيرٌ» خَرَجَ مِنْ ذُنُوبِهِ كَيَوْمَ وَلَدَتْهُ أُمُّهُ.
Bakr ibn Muhammad reported that Imam عليه السلام said: "Whoever says the following three times when taking their place to sleep: 'All praise is due to Allah سبحانه وتعالى, Who is exalted and dominates. All praise is due to Allah سبحانه وتعالى, Who is hidden yet knows. All praise is due to Allah سبحانه وتعالى, Who rules and controls with power. All praise is due to Allah سبحانه وتعالى, Who gives life to dead and causes living to die, and is over all things capable,' will be free of sins as on the day their mother gave birth to them."
