Dua before sleeping

‘When retiring to his bed every night, the Prophet (S) would hold his palms together, spit (A form of spitting comprising mainly of air with little spittle) in them, recite the last three chapters (Al-Ikhlas, Al-Falaq, An-Nas) of the Quran and then wipe over his entire body as much as possible with his hands, beginning with his head and face and then all parts of the body, he would do this three times.’

{اللّهُ لاَ إِلَـهَ إِلاَّ هُوَ الْحَيُّ الْقَيُّومُ لاَ تَأْخُذُهُ سِنَةٌ وَلاَ نَوْمٌ لَّهُ مَا فِي السَّمَاوَاتِ وَمَا فِي الأَرْضِ مَن ذَا الَّذِي يَشْفَعُ عِنْدَهُ إِلاَّ بِإِذْنِهِ يَعْلَمُ مَا بَيْنَ أَيْدِيهِمْ وَمَا خَلْفَهُمْ وَلاَ يُحِيطُونَ بِشَيْءٍ مِّنْ عِلْمِهِ إِلاَّ بِمَا شَاء وَسِعَ كُرْسِيُّهُ السَّمَوَاتِ وَالأَرْضَ وَلاَ يَؤُودُهُ حِفْظُهُمَا وَهُوَ الْعَلِيُّ الْعَظِيمُ }

The Prophet (S) also said: ‘When you are about to sleep recite ayat-al-kursee (The verse of the foot-stool, chapter 2:255) till the end of the verse for there will remain over you a protection from Allah and no devil will draw near to you until morning.’

{آمَنَ الرَّسُولُ بِمَا أُنزِلَ إِلَيْهِ مِن رَّبِّهِ وَالْمُؤْمِنُونَ كُلٌّ آمَنَ بِاللّهِ وَمَلآئِكَتِهِ وَكُتُبِهِ وَرُسُلِهِ لاَ نُفَرِّقُ بَيْنَ أَحَدٍ مِّن رُّسُلِهِ وَقَالُواْ سَمِعْنَا وَأَطَعْنَا غُفْرَانَكَ رَبَّنَا وَإِلَيْكَ الْمَصِيرُ * لاَ يُكَلِّفُ اللّهُ نَفْساً إِلاَّ وُسْعَهَا لَهَا مَا كَسَبَتْ وَعَلَيْهَا مَا اكْتَسَبَتْ رَبَّنَا لاَ تُؤَاخِذْنَا إِن نَّسِينَا أَوْ أَخْطَأْنَا رَبَّنَا وَلاَ تَحْمِلْ عَلَيْنَا إِصْراً كَمَا حَمَلْتَهُ عَلَى الَّذِينَ مِن قَبْلِنَا رَبَّنَا وَلاَ تُحَمِّلْنَا مَا لاَ طَاقَةَ لَنَا بِهِ وَاعْفُ عَنَّا وَاغْفِرْ لَنَا وَارْحَمْنَا أَنتَ مَوْلاَنَا فَانصُرْنَا عَلَى الْقَوْمِ الْكَافِرِينَ }

The Prophet (S) also said: ‘Whoever recites the last two verses of Soorat Al-Baqarah at night, those two verses shall be sufficient for him (i.e. protect him from all that can cause him harm).’

بِاسْمِكَ رَبِّي وَضَعْتُ جَنْبِي، وَبِكَ أَرْفَعُهُ، فَإِنْ أَمْسَكْتَ نَفْسِي فَارْحَمْهَا، وَإِنْ أَرْسَلْتَهَا فَاحْفَظْهَا بِمَا تَحْفَظُ بِه ِِ عِبَادَكَ الصَّالِحِيْنَ

‘If one of you rises from his bed and then returns to it he should dust it with the edge of his garment three times for he does not know what has occurred in his absence and when he lies down he should supplicate:
‘In Your name my Lord, I lie down and in Your name I rise, so if You should take my soul then have mercy upon it, and if You should return my soul then protect it in the manner You do so with Your righteous servants.’

اللَّهمَّ إِنَّكَ خَلَقْتَ نَفْسِي وَأَنْتَ تَوَفَّاهَا لَكَ مَمَاتُهَا وَمَحْيَاهَا، إِنْ أَحْيَيْتَهَا فَاحْفَظْهَا، وَإِنْ أَمَتَّهَا فَاغْفِرْ لَهَا. اللَّهمَّ إِنِّي أَسْأَلُكَ العَافِيَةَ

‘O Allah, verily You have created my soul and You shall take it’s life, to You belongs it’s life and death. If You should keep my soul alive then protect it, and if You should take it’s life then forgive it. O Allah, I ask You to grant me good health.’

اللَّهمَّ قِنِي عَذَابَكَ يَوْمَ تَبْعَثُ عِبَادَكَ. (ثَلاثا)ً

The Prophet (S) would place his right hand under his cheek when about to sleep and supplicate:
(100) Al-Lahumma Qini Adhabaka Yawma Tab athu Ibadak. (three times)

بِاسْمِكَ اللَّهمَّ أَمُوْتُ وَأَحْيَا

‘In Your name O Allah, I live and die.’

سُبْحَانَ اللَّهِ. (ثَلاثا ً وَثَلاثِيْن) الحَمْدُ للهِ. (ثَلاثا ً وَثَلاثِيْن) اللَّهُ أَكْبَرُ. (أَرْبَعا ً وَثَلاثِيْن)

‘Shall I not direct you both (The Prophet (the Peace and Blessings of Allah be upon him) was addressing Ali and Fatimah-may Allah be pleased with them when they approached him for a servant) to something better than a servant? When you go to bed say:
Subhanal-Lāh. (thirty-three times)
Al-Ĥamdu Lillāh. (thirty-three times)
Allāhu ‘Akbar. (thirty-four times)
….for that is indeed better for you both than a servant.’

اللَّهمَّ رَبَّ السَّمَوَاتِ السَّبْعِ وَرَبَّ العَرْشِ العَظِيْمِ، رَبَّنَا وَرَبَّ كُلِّ شَيء، ٍ فَالِقَ الحَبِّ وَالنَّوَى، وَمُنَزِّلَ التَّوْرَاةِ وَالإِنْجِيْلِ، وَالفُرْقَانِ، أَعُوْذُ بِكَ مِنْ شَرِّ كُلِّ شَيءٍ أَنْتَ آخِذ ٌ بِنَاصِيَتِهِ. اللَّهمَّ أَنْتَ الأَوَّلُ فَلَيْسَ قَبْلَكَ شَيء، ٌ وَأَنْتَ الآخِرُ فَلَيْسَ بَعْدَكَ شَيء، ٌ وَأَنْتَ الظَّاهِرُ فَلَيْسَ فَوْقَكَ شَيء، ٌ وَأَنْتَ البَاطِنُ فَلَيْسَ دُوْنَكَ شَيء، ٌ اقْضِ عَنَّا الدَّيْنَ وَأَغْنِنَا مِنَ الفَقْر

‘O Allah, Lord of the seven heavens and the exalted throne, our Lord and Lord of all things, Splitter of the seed and the date stone, Revealer of the Tawrah, the Injeel and the Furqan, I take refuge in You from the evil of all things You shall seize by the forelock (i.e. You have total mastery over). O Allah, You are The First so there is nothing before You and You are The Last so there is nothing after You.You are Aththahir so there is nothing above You and You are Al-Batin so there is nothing closer than You.Settle our debt for us and spare us from poverty.’

الحَمْدُ للهِ الَّذِي أَطْعَمَنَا وَسَقَانَا، وَكَفَانَا، وَآوَانَا، فَكَمْ مِمَّنْ لا كَافِيَ لَه ُُ وَلا مُؤْوِي

All praise is for Allah, Who fed us and gave us drink, and Who is sufficient for us and has sheltered us, for how many have none to suffice them or shelter them.’

اللَّهمَّ عَالِمَ الغَيْبِ وَالشَّهَادَةِ فَاطِرَ السَّمَاوَاتِ وَالأَرْضِ رَبَّ كُلِّ شَيء ٍ وَمَلِيْكَهُ، أَشْهَدُ أَنْ لا إِلَهََ إِلاَّ أَنْتَ، أَعُوْذُ بِكَ مِنْ شَرِّ نَفْسِي، وَمِنْ شَرِّ الشَّيْطَانِ وَشِرْكِهِ، وَأَنْ أَقْتَرِفَ عَلَى نَفْسِي سُوْءاً أَوْ أَجُرَّهُ~ُ إِلَى مُسْلِم

‘O Allah, Knower of the seen and the unseen, Creator of the heavens and the earth, Lord and Sovereign of all things I bear witness that none has the right to be worshipped except You. I take refuge in You from the evil of my soul and from the evil and shirk of the devil, and from committing wrong against my soul or bringing such upon another Muslim.’
Notes:
shirk: to associate others with Allah in those things which are specific to Him. This can occur in (1) belief, e.g. to believe that other than Allah has the power to benefit or harm, (2) speech, e.g. to swear by other than Allah and (3) action, e.g. to bow or prostrate to other than Allah.

“يَقْرَأُ سُوْرَةَ السَّجْدَةِ {ألم }، وَسُوْرَةَ المُلْكِ {تَبَارَكَ الَّذِي بِيَدِهِ المُلْكُ}”

‘The Prophet (the Peace and Blessings of Allah be upon him) never used to sleep until he had recited Sura As-Sajdah (chapter 32) and Sura Al-Mulk (chapter 67).’
