📖Sahih al-Bukhari 6311
Narrated Al-Bara bin `Azib:
Allah’s Messenger (ﷺ) said to me, “When you want to go to bed, perform ablution as you do for prayer, then lie down on your right side and say:

اللَّهُمَّ أَسْلَمْتُ وَجْهِي إِلَيْكَ، وَفَوَّضْتُ أَمْرِي إِلَيْكَ، وَأَلْجَأْتُ ظَهْرِي إِلَيْكَ، رَغْبَةً وَرَهْبَةً إِلَيْكَ، لا مَلْجَأَ وَلا مَنْجَا مِنْكَ إِلَّا إِلَيْكَ، آمَنْتُ بِكِتَابِكَ الَّذِي أَنْزَلْتَ وَبِنَبِيِّكَ الَّذِي أَرْسَلْتَ
“O Allah, I submit my face to You, entrust my affairs to You, and rely on You, in hope and fear of You. There is no refuge or escape from You except with You. I believe in Your Book which You have revealed and in Your Prophet whom You have sent.”

Then the Prophet ﷺ added:
“If you should die then (after reciting this) you will die on the religion of Islam; so let these be the last words you say (before sleeping).”
When I (Al-Bara) repeated it, I said, “…wa birasulika (in Your Messenger),” but the Prophet corrected me:
“No, say: wa binabiyyika (in Your Prophet whom You have sent).”

Description

This hadith isn’t just about sleeping – it’s about how to end your day in submission, trust, and faith.

1. Wudu before sleeping: Staying physically and spiritually clean. Science today shows sleeping with ablution can calm the mind and improve sleep quality.
2. Sleeping on the right side: Sunnah and now confirmed by modern health studies as better for digestion and heart pressure.
3. Powerful du’a: Declaring total surrender to Allah – mind, body, and soul – showing reliance, hope, and belief in the Qur’an and the Prophet ﷺ.

The correction by the Prophet (from rasulika to nabiyyika) teaches us precise language matters in faith. He was sent as both Messenger (Rasul) and Prophet (Nabi), but this specific du’a uses Nabi for its deeper spiritual role.

Some might say: “Why follow such steps every night? It’s old-fashioned. Past people did it out of fear or ritual — we are modern”

But here’s the logical perspective:

• Psychology of sleep: What you say and feel before sleep shapes your mental state, dreams, and emotional regulation. This du’a is full of trust, surrender, hope, and remembrance. That gives peace.
• Cleanliness (wudu): Science now confirms that washing face, hands, and feet before sleep reduces stress, improves sleep hygiene, and even calms the nervous system.
• Right-side sleep: Health professionals agree – it reduces heartburn and promotes better circulation.
• Death reminder: You may not wake up. What better last words than faith in Allah, His Book, and His Prophet? Logical? Yes. Spiritually priceless? Absolutely.

Quranic Context:

📖Quran 3:191
Those who remember Allah while standing or sitting or lying on their sides and reflect on the creation of the heavens and the earth, saying: “Our Lord, You have not created all of this without purpose. Glory be to You! Protect us from the punishment of the Fire.”

This hadith is a direct fulfillment of that verse – remembering Allah even while lying on your side before sleep.
