Abu Sa`eed (ra) narrated that: the Prophet ( صلی اللہ علیہ وسلم ) said:“Whoever says, when he goes to his bed: ‘I seek forgiveness from Allah, [the Magnificent] the One whom there is none worthy of worship except for Him, the Living, the Sustainer, and I repent to Him (Astaghfirullāha [al-`Aẓim] alladhi lā ilāha illā huw, al-Ḥayyul-Qayyūm, wa atūbu ilaihi)’ three times, Allah shall forgive him his sins if they were like the foam of the sea, even if they were the number of leaves of the trees, even if they were the number of sand particles of `Alij, even if they were the number of the days of the world.”

Hudhaifah bin Al-Yaman (ra) narrated that: When the Prophet ( صلی اللہ علیہ وسلم ) would sleep, he would put his hand under his head then say:“O Allah, safeguard me from Your Punishment the Day You gather [Your slaves] (Allāhumma qinī `adhābaka yawma tajma`u [`ibādak] )”or“you resurrect your slaves (tab`athu `ibādak).”

Al-Bara' bin `Azib (ra) narrated that: The Messenger of Allah ( صلی اللہ علیہ وسلم ) used to lay his head upon his right hand when going to sleep, then say:“My Lord, safeguard me from Your punishment the Day You resurrect Your slaves (Rabbi qinī `adhābaka yawma tab`athu `ibādak).”

Abu Hurairah (ra) said:`“The Messenger of Allah ( صلی اللہ علیہ وسلم ) used to order that when one of us went to sleep, he should say: ‘O Allah, Lord of the heavens and Lord of the earths, and our Lord, and the Lord of everything, splitter of the seed-grain and date-stone, and Revealer of the Tawrah and the Injil and the Qur’an. I seek refuge in You from the evil of every evil that You are holding by the forelock. You are the First, there is nothing before You, You are the Last, there is nothing after You, and Az-Zahir, there is nothing above you, and Al-Batin, there is nothing below You. Relieve me of my debt, and enrich me from poverty (Allāhumma rabbas-samāwati wa rabbal-arḍīna wa rabbanā, wa rabba kulli shai’in, fāliqal-ḥabbi wan-nawā, wa munzilat-Tawrāti wal-Injīli wal-Qur’ān. A`ūdhu bika sharri kulli dhi sharrin anta ākhidhun bināṣiyatihi, antal-Awwalu falaisa qablaka shai’un, wa antal-Ākhiru falaisa ba`daka shai’un, waẓ-Ẓāhiru falaisa fauqaka shai'un wal-Bātinu falaisa dūnaka shai’un, iqḍi `annid-daina wa aghninī minal-faqr).’”

Abu Hurairah (ra) narrated that: the Messenger of Allah ( صلی اللہ علیہ وسلم ) said:“When one of you leaves his bed then returns to it, then let him brush it off with the edge of his Izar three times, for indeed, he does not know what succeeded him upon it after him. When he lies down, let him say: ‘In Your Name, my Lord, I lay my side down, and in Your Name I raise it. And if You take my soul, then have mercy upon it, and if You release it, then protect it with that which You protect Your righteous worshipers (Bismika rabbī waḍa`tu janbī wa bika arfa`uhu, fa’in amsakta nafsī farḥamhā wa in arsaltahā faḥfaẓhā bimā taḥfaẓu bihī `ibādakaṣ-ṣāliḥīn)’ And when he awakens, let him say: All praise is due to Allah, Who healed me in my body, and returned to me my soul, and permitted me to remember Him (Al-ḥamdulillāh alladhī `āfānī fī jasadī wa radda `alayya rūḥī wa adhina lī bidhikrih).’”

Aishah narrated that: Every night, when the Prophet ( صلی اللہ علیہ وسلم ) would go to his bed, he would join his hands, then blow in them, as he recited in them:“Say: He is Allah, the One.”And“Say: I seek refuge in the Lord of Al-Falaq”and“Say: I seek refuge in the Lord of mankind.”Then he would wipe as much as he was able to of his body with them, beginning with them first of his head and face, and the front of his body. He would do this three times.

Farwah bin Nawfal (ra) narrated that: He came to the Prophet ( صلی اللہ علیہ وسلم ) and said:“O Messenger of Allah, teach me something that I may say when I go to my bed.”So he said:“Recite: Say: ‘O you disbelievers’ for verily it is a disavowal of Shirk.”Shu`bah said:“Sometimes he would say: ‘One time’ and sometime he would not say it.”(Another chain) from Farwah bin Nawfal, from his father: "That he came to the Prophet ( صلی اللہ علیہ وسلم )" then he mentioned similar in meaning. And this is more correct. [Abu `Eisa said:] And Zubair reported this hadith from Ishaq, from Farwah bin Nawfal, from his father from the Prophet ( صلی اللہ علیہ وسلم ), with similar wording. This is more appropriate and more correct than the narration of Shu`bah. The companions of Abu Ishaq were confused in the narration of this hadith. This hadith has been reported through routes other than this. `Abdur-Rahman is the brother of Farwah bin Nawfal.

Israel narrated from Abu Ishaq, and Abu Ishaq from Farwah bin Nawfal, and Farwah from his father Nawfal, that he came to the Prophet (peace and blessings of Allah be upon him), then he mentioned a hadith similar in meaning to the previous hadith. Imam Tirmidhi says:
1- And this narration is more authentic,
2- Also, Zuhair narrated this hadith from Abu Ishaq, Abu Ishaq from Farwah bin Nawfal, Farwah from his father Nawfal, and Nawfal from the Prophet (peace and blessings of Allah be upon him) in the same way, and this narration is more similar and more authentic than the narration of Shu’bah. And the companions (students) of Abu Ishaq are confused in this hadith,
3- This hadith has also come through other chains besides this chain; this hadith was also narrated by Abdur Rahman bin Nawfal from his father (Nawfal), and Nawfal from the Prophet (peace and blessings of Allah be upon him), and Abdur Rahman is the brother of Urwah bin Nawfal.

Jabir said:`“The Prophet would not sleep until he reached Tanzil as-Sajdah and Tabarak.”

`A'isha (ra) said:`“The Prophet ( صلی اللہ علیہ وسلم ) would not sleep until he recited Az-Zumar and Banu Isra’il.”Muhammad bin Ismail informed me:“This Abu Lubabah’s (a narrator in the chain) name is Marwan, the freed slave of Abdur-Rahman bin Ziyad. He heard from Aisha, and Hammad bin Zaid heard from him.”
