Abu Dawud

Benefits and Issues:
➊
It is Sunnah to dust off the bed before sleeping.

➋
The final words of the supplication mentioned in the hadith (as-salihin min ‘ibadika) are also found in some hadith books as (‘ibadika as-salihin). Therefore, both versions of the wording are correct in the supplication.
See:
(Sahih al-Bukhari, Kitab ad-Da‘awat, Hadith: 6320)

Hadith Commentary:
(1)
If someone comes to his bed to sleep, he should dust it off with the edge of his sheet, because it is possible that, without his knowledge, some poisonous creature or insect may have come onto the bed.
It is recommended to dust with the sheet instead of the hand so that his hand is not harmed in any way by a harmful creature.
(Fath al-Bari: 11/152)
(2)
In addition to the mentioned supplication, other supplications can also be recited at this time, as mentioned in many hadiths.
In some narrations, dusting the bed three times is also mentioned (Sahih al-Bukhari, al-Tawhid, Hadith: 7393),
so that this act resembles the practice of blowing (for protection) and similar actions.
(Fath al-Bari: 11/152)

Hadith Commentary:
The narrations of Muhammad bin Abdur Rahman Tufawi and Usamah bin Hafs have already appeared in this very book with a connected (musnad) chain, and the narration of Abdul Aziz has been connected (mawsul) by ‘Adi radi Allahu anhu.

Hadith Commentary:
➊
Ibn Battal said that in this narration, attribution of “placing” (wada‘) is to the name, and attribution of “raising” (rafa‘) is to the essence (dhat). From this, it is understood that by “name” is meant the essence itself; in placing and raising, assistance is sought from the essence, not from the word.
(Fath al-Bari: 13/464)
➋
Ibn Battal has, in his own manner, derived relevance from this hadith, whereas Imam Bukhari rahimahullah certainly did not have this objective.
According to our inclination, a sincere servant worships Allah Ta‘ala at all times, fulfills all matters of life according to the will of his Lord, and seeks the pleasure of Allah Ta‘ala when leaving his house, entering his house, eating and drinking, sleeping and waking, and in interacting with people.
➌
In this hadith, the Messenger of Allah sallallahu alayhi wa sallam has provided guidance on worshiping at the time of sleep and upon awakening from it: how a person should lay his side on the bed through the name of Allah Ta‘ala and ask Him by His names.
In reality, sleep is a kind of death; sometimes a person passes away in the state of sleep. Therefore, the Messenger of Allah sallallahu alayhi wa sallam taught that one should invoke the name of Allah Ta‘ala and supplicate to Him.
If death comes, may Allah Ta‘ala forgive him.
And if, by His perfect power, He returns the soul to the body, may He protect him from Satan and other harmful things.
According to this hadith, mentioning Allah Ta‘ala at the time of sleep is legislated, so that a person’s minor death—that is, sleep—occurs upon the name of Allah Ta‘ala, and he becomes a living embodiment of this verse:
“Say: Indeed, my prayer, my sacrifice, my life, and my death are for Allah, the Lord of the worlds.”
()
In this manner, a person entrusts himself to Allah Ta‘ala and expresses his humility, helplessness, and neediness before Him, asking Allah Ta‘ala for everything without which he is not self-sufficient.
All of this is worship of Allah Ta‘ala and calling upon Him by His names; it is as if it is a commentary on this verse:
“The most beautiful names belong to Allah, so call upon Him by them.”
()
On the basis of this relevance, Imam Bukhari rahimahullah has mentioned this hadith here.

Hadith Commentary:
Benefits and Issues:
Whatever we eat and drink,
the shelters that are available to us, and our needs that are being fulfilled—
in other words, whatever we are receiving—
all of it is a gift from our Merciful Lord. Therefore, He alone is deserving of praise and gratitude.
In this way, through this acknowledgment of reality and through supplication, we can express gratitude to Allah for all those blessings
from which we are benefiting.

Explanation:
1:
O my Lord! I am laying my side (on my bed) by taking Your name, that is, I am going to sleep, and I will also raise it by taking Your name. Then if You withhold my soul (i.e., cause me to die) while I am sleeping, then have mercy on my soul. And if You let me live, then protect it in the same manner as You protect Your righteous and pious servants.

2:
All praise is due to Allah who kept my body healthy, returned my soul to me, and granted me permission (and ability) to remember Him.

Benefits and Issues:

➊ Before lying down on the bed, one should dust it off, lest there be any harmful creature such as a scorpion or an ant, which could cause harm.

➋ Supplicating to Allah is the best means of protection.

➌ Exercising caution and adopting protective measures is not contrary to reliance (tawakkul) upon Allah.

➍ When a person goes to sleep, he should reflect that it may be his last sleep; therefore, he should seek forgiveness from Allah and remember Him, and lie down to rest in the prescribed (masnun) manner.
