The Sunan of Sleep:

“Turn off any lamps when you go to bed, shut the doors, and cover containers of water and food.”

“… and lock your doors and mention Allāh’s name, as the devil does not open a locked door.”

“Do not leave the fire burning in your homes when you go to bed.”

“When you want to go to bed, perform ablution as you do for prayer, then lie down on your right side and say, ‘O Allāh, I submitted my face towards You ...’.”

“When one of you goes to bed, he should dust his bed off with the inner side of his lower garment, for he does not know what came onto it after he left it. He should then say, ‘In Your name, my Lord, I lie down, and in Your name I rise. If You take my soul then show mercy on it, and if You return it then protect it as You protect Your righteous slaves.’.”

“Upon going to bed, perform ablution as you do for prayer, then lie down on your right side and say, ‘O Allāh, I submitted my face towards You ...’.”

“The Prophet (PBUH) would put his right hand under his cheek when he lied down for sleep at night.”

“... Then the Prophet (PBUH) asked me, ‘What did your prisoner do last night?’ I answered, ‘He promised to teach me some words which he claimed will benefit me before Allāh, so I let him go.’ The Prophet (PBUH) asked, ‘What are those words that he taught you?’ I said, ‘He told me, “When you go to bed, recite Āyat Al-Kursiy from its beginning to its end. If you do so, a guardian will be appointed by Allāh to protect you during the night, and no devil will be able to approach you until the morning.’ The Prophet (PBUH) said, ‘Verily, he told you the truth although he is a liar. O Abā Hurayrah, do you know with whom you were speaking for the last three nights?’ I said, ‘No.’ The Prophet (PBUH) replied, ‘That was a devil.’.”

“Whoever recites the last two verses of Soorat Il-Baqarah at night, they shall be sufficient for him.”

“When the Messenger of Allāh  would go to bed every night, he would bring his hands together and blow in them, and he would recite in them Soorat Al-Ikhlās, Soorat Al-Falaq, and Soorat An-Nās, then he would wipe with them over whatever he is able to reach of his blessed body, starting at his head and face, then moving to the rest of his body. He would do this three times.”

“Recite Soorat Al-Kāfiroon and let it be the last thing you recite before you sleep, for it clears you from Shirk (polytheism).”

{ بِاسْمِكَ اللَّهُمَّ أَمُوتُ وَأَحْيَا }

“O Allāh by Your name I die and I revive.”

{ اللَّهُمَّ خَلَقْتَ نَفْسِي وَأَنْتَ تَوَفَّاهَا، لَكَ مَمَاتُهَا وَمَحْيَاهَا، إِنْ أَحْيَيْتَهَا فَاحْفَظْهَا، وَإِنْ أَمَتَّهَا فَاغْفِرْ لَهَا، اللَّهُمَّ إِنِّي أَسْأَلُكَ الْعَافِيَةَ }

“O Allāh, You have created my soul and You take it back. Unto You is its death and its life. If You give it life then protect it, and if You cause it to die then forgive it. O Allāh, I ask You well-being.”

{ اللَّهُمَّ رَبَّ السَّمَاوَاتِ وَرَبَّ الأَرْضِ وَرَبَّ الْعَرْشِ الْعَظِيمِ , رَبَّنَا وَرَبَّ كُلِّ شَيْءٍ, فَالِقَ الْحَبِّ وَالنَّوَى , وَمُنْزِلَ التَّوْرَاةِ وَالإِنْجِيلِ وَالْفُرْقَانِ , أَعُوذُ بِكَ مِنْ شَرِّ كُلِّ شَيْءٍ أَنْتَ آخِذٌ بِنَاصِيَتِهِ , اللَّهُمَّ أَنْتَ الأَوَّلُ فَلَيْسَ قَبْلَكَ شَيْءٌ , وَأَنْتَ الآخِرُ فَلَيْسَ بَعْدَكَ شَيْءٌ , وَأَنْتَ الظَّاهِرُ فَلَيْسَ فَوْقَكَ شَيْءٌ , وَأَنْتَ الْبَاطِنُ فَلَيْسَ دُونَكَ شَيْءٌ , اقْضِ عَنَّا الدَّيْنَ وَأَغْنِنَا مِنَ الْفَقْرِ }

“O Allāh, Lord of the seven heavens and Lord of the Magnificent Throne. Our Lord and the Lord of everything. Splitter of the grain and seeds, Revealer of the Torah and the Injeel and the Furqān (i.e. the Qur’ān), I seek refuge in You from every evil that You seize by the forelock. O Allāh, You are the First and nothing has come before you, and You are the Last and nothing may come after You. You are the Evident and nothing is above You, and You are the Innermost and nothing is beyond You. Remove our burdens of debt and enrich us against poverty.”

{ بِاسْمِكَ رَبِّ وَضَعْتُ جَنْبِي وَبِكَ أَرْفَعُهُ إِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِهِ عِبَادَكَ الصَّالِحِينَ }

“With Your Name, my Lord, I laid myself down, and with Your Name I rise. If You take my soul show mercy on it, and if You send it back then protect it like You protect Your righteous slaves.”

{ الْحَمْدُ للّهِ الَّذِي أَطْعَمَنَا وَسَقَانَا، وَكَفَانَا وَآوَانَا, فَكَمْ مِمَّنْ لاَ كَافِيَ لَهُ وَلاَ مُؤْوِي }

“Upon going to bed, Allāh’s Messenger used to say, ‘Praise be to Allāh who fed us, gave us drink, gave us what is sufficient for us, and gave us shelter. Many are those who have no one to provide sufficiency for them or give them shelter.’.”

{ اللَّهُمَّ قِنِي عَذَابَكَ يَوْمَ تَبْعَثُ عِبَادَكَ }

“O Allāh, protect me against Your punishment on the day You resurrect Your slaves.”

“So the Prophet came to us when we had gone to bed. We wanted to get up on his arrival but he said, ‘Stay where you are.’ He then came and sat between me and her and I felt the coldness of his feet on my chest. He said, ‘Shall I direct you to something better than what you have requested? When you go to bed say “Allāhu Akbar” thirty-four times, “Subhān Allāh” thirty-three times, and “Al-Hamdu Lillāh” thirty-three times, for that is far better for you than a servant.’.”

“I have never left them since I heard about them from the Prophet (PBUH).” He was asked, “Even on the night of the battle of Siffeen?” He said, “Even on the night of the battle of Siffeen.”

{ اللَّهُمَّ إِنِّي أَسْلَمْتُ وَجْهِي إِلَيْكَ ، وَفَوَّضْتُ أَمْرِي إِلَيْكَ ، وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ ، رَغْبَةً وَرَهْبَةً إِلَيْكَ. لاَ مَلْجَأَ وَلاَ مَنْجَا مِنْكَ إِلاَّ إِلَيْكَ, آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ ، وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ }

“O Allāh, I submitted my face to You, entrusted my affairs to You, and relied completely on You, out of desire and fear of You. There is no resort or escape from You except with You. I believe in Your Book that You have revealed, and in Your Prophet whom You have sent.”

“… and make them of the last of what you utter before sleeping, so if you die during the night, you will have died while you are on the Fitrah (i.e. natural disposition)”

“… and if you wake up in the morning, you will have woken up on well-being.”

{ سَيِّدُ الِاسْتِغْفَارِ أَنْ يَقُولَ: اللَّهُمَّ أَنْتَ رَبِّي لَا إِلَهَ إِلَّا أَنْتَ خَلَقْتَنِي وَأَنَا عَبْدُكَ وَأَنَا عَلَى عَهْدِكَ وَوَعْدِكَ مَا اسْتَطَعْتُ أَعُوذُ بِكَ مِنْ شَرِّ مَا صَنَعْتُ أَبُوءُ لَكَ بِنِعْمَتِكَ عَلَيَّ وَأَبُوءُ بِذَنْبِي فَاغْفِرْ لِي إِنَّهُ لَا يَغْفِرُ الذُّنُوبَ إِلَّا أَنْتَ ، قَالَ: وَمَنْ قَالَهَا مِنْ النَّهَارِ مُوقِنًا بِهَا فَمَاتَ مِنْ يَوْمِهِ قَبْلَ أَنْ يُمْسِيَ فَهُوَ مِنْ أَهْلِ الْجَنَّةِ، وَمَنْ قَالَهَا مِنْ اللَّيْلِ وَهُوَ مُوقِنٌ بِهَا فَمَاتَ قَبْلَ أَنْ يُصْبِحَ فَهُوَ مِنْ أَهْلِ الْجَنَّةِ }

“The most superior way of asking Allāh forgiveness is, ‘O Allāh, you are my Lord. There is no God worthy of worship but You. You created me and I am Your servant, and I uphold Your covenant and my promise to You to the most of my ability. I seek refuge in You from the evil I have done. I acknowledge before You Your favor upon me, and I acknowledge my sin; so forgive me, as indeed, there is none who can forgive sins except You.’.” The Prophet (PBUH) added, “Whoever peforms this supplication in the morning with firm faith in it and dies on the same day will be from the people of Paradise, and whoever peforms it in the night with firm faith and dies during the same night will be from the people of Paradise.”
