The Adab of Sleeping & Waking

The Ruling: Sleep as an Act of Worship

Islam does not leave any part of the believer's day without guidance, and sleep — nearly a third of a person's life — is no exception. The Prophet (ﷺ) taught his companions a settled routine for retiring at night: purifying oneself, preparing the bed, reciting protective revelation, lying in a specific posture, and sealing the day with words of remembrance. These practices are, by the agreement of the scholars, Sunnah mustaḥabbah (recommended and rewarded) rather than obligatory; a person who sleeps without them has not sinned, but he has left behind great reward and lost a nightly fortress of protection.

The wisdom is unmistakable. The one who falls asleep in a state of wuḍūʾ, having sought refuge in the Words of Allah, has made his very unconsciousness an act of ʿibādah. He surrenders his soul to Allah in submission, and if death comes to him in that state — for sleep is 'the lesser death' — he departs upon īmān and the fitrah. This is why the adab of sleep is treated in the books of the Sunnah not as folk custom but as authentic prophetic teaching, transmitted with rigorous chains.

Purity and Preparing the Bed

The first sunnah of the night is to sleep in a state of purity. Al-Barāʾ ibn ʿĀzib (رضي الله عنه) reported that the Prophet (ﷺ) instructed him to perform wuḍūʾ as for prayer before lying down. Performing wuḍūʾ before sleep is recommended for everyone, and is especially emphasised for the one in a state of major impurity (janābah), as established in other authentic reports where ʿUmar asked about this and was told to perform wuḍūʾ and then sleep.

The second sunnah is to dust off the bedding before lying down. Abū Hurayra (رضي الله عنه) reported the Prophet's instruction to shake out one's bed with the inner edge of one's garment while mentioning the name of Allah, "for he does not know what came onto his bed after him." This is both a practical hygiene and a prophetic caution, and the scholars recommend doing it three times.

The Nightly Fortress: Recitation Before Sleep

The Prophet (ﷺ) turned the moments before sleep into a shield of revelation. Foremost among these is the recitation of the three protective sūrahs. ʿĀʾisha (رضي الله عنها) reported that each night before sleeping he would cup his hands, recite Sūrat al-Ikhlāṣ, al-Falaq and al-Nās into them, blow gently, and then wipe over as much of his body as he could reach, beginning with his head, face and the front of his body — repeating this three times.

Second is Āyat al-Kursī (al-Baqarah 2:255). In a well-known narration, Abū Hurayra (رضي الله عنه) was told by a thief he had caught — who turned out to be a shayṭān — that whoever recites Āyat al-Kursī when going to bed will have a guardian from Allah, and no devil will approach him until morning. When Abū Hurayra reported this, the Prophet (ﷺ) confirmed: "He told you the truth, though he is a liar."

Third is the recitation of the final two verses of Sūrat al-Baqarah (2:285–286). The Prophet (ﷺ) taught that whoever recites them at night, they will suffice him — understood by the scholars to mean they suffice him against every harm, or in place of the night prayer, or both.

Finally, the day is sealed with the supplication of surrender taught in the ḥadīth of al-Barāʾ — and the Prophet (ﷺ) stressed that it be the very last speech before sleep, so that one departs into the night upon these words of tawḥīd and reliance.

Posture: The Sunnah and the Points of Difference

The established Sunnah is to lie down on the right side, as commanded in the ḥadīth of al-Barāʾ above. Scholars mention several wisdoms for this, including that it is lighter on the heart and helps a person wake more readily for prayer, though the ruling stands on the text regardless of the wisdom. Placing the right hand under the right cheek is also reported in the Sunnah.

Sleeping on the back is permissible and carries no blame. It is authentically established that the Prophet (ﷺ) himself was seen lying on his back in the mosque, one leg placed over the other, so the recommendation of the right side does not render other postures forbidden.

Sleeping on the stomach (prone) is held to be disliked by most scholars. The narration usually cited for it is in the Sunan rather than in the two Ṣaḥīḥ collections, and this site's own hadith repository grades it ḍaʿīf — so it is not quoted here as evidence. The preference for the right side above rests on narrations that are ṣaḥīḥ, and that is the guidance this page stands on.

Rising Upon the Fitrah

Just as the believer surrenders his soul at night, he receives it back at dawn with gratitude. Ḥudhayfa ibn al-Yamān (رضي الله عنه) reported that when the Prophet (ﷺ) lay down to sleep he would say, "In Your name, O Allah, I die and I live," and when he awoke he would praise Allah for restoring life after this lesser death.

In this daily cycle the believer rehearses the greatest of realities: death, and the return to Allah. He falls asleep having entrusted his soul to its Owner, protected by revelation and lying upon the Sunnah; and he rises to a new day in gratitude, upon the fitrah — the pure natural state upon which Allah created His servants. This is the fruit that the ḥadīth of al-Barāʾ promised to the one who seals his night with these words: "if you die that night, you will die upon the fitrah."
