Four surahs. Each beginning with the word Qul — Say. A divine instruction before a declaration. Say this. Mean this. Let these words be your position. Together they cover the foundations of Islamic belief, the rejection of false worship, and comprehensive protection from every form of harm.
The four are: Surah Al-Kafirun (109), Surah Al-Ikhlas (112), Surah Al-Falaq (113), and Surah An-Nas (114). Each deserves individual attention.
Surah Al-Kafirun — the disavowal of shirk
“Say: O disbelievers — I do not worship what you worship, nor do you worship what I worship. Nor will I be a worshipper of what you worship, nor will you be worshippers of what I worship. For you is your religion, and for me is my religion.” (Quran 109)
Uqba ibn Amir ؓ reported that the Prophet ﷺ said: “Recite Qul ya ayyuhal kafirun when you go to sleep — for it is a disavowal from shirk.” (Abu Dawud · 5055). The surah draws a clean line. It doesn’t negotiate with false worship or seek middle ground. Reciting it before sleep is a nightly renewal of that clarity.
Surah Al-Ikhlas — equal to a third of the Quran
The Prophet ﷺ said: “By the One in whose hand my soul is, it is equal to a third of the Quran.” (Bukhari · 5013, Muslim · 811 — sahih)
Four verses. The entire concept of tawhid — the absolute oneness of Allah ﷻ — compressed into the most precise language possible. He is One. He is the Eternal Refuge. He neither begets nor is begotten. And there is nothing comparable to Him. When the Companions asked why it equates to a third of the Quran, the Prophet ﷺ explained it comprehends a third of the Quran’s content — the knowledge of Allah ﷻ Himself.
A man told the Prophet ﷺ he loved Surah Al-Ikhlas. The Prophet ﷺ said: “Your love for it will enter you into paradise.” (Bukhari · 7375). Love of the surah that describes Allah ﷻ most purely — is itself a path to Him.
Surah Al-Falaq — seeking refuge from external harm
“Say: I seek refuge in the Lord of daybreak — from the evil of what He has created, from the evil of darkness when it settles, from the evil of those who blow on knots, and from the evil of an envier when he envies.” (Quran 113)
This surah was revealed when the Prophet ﷺ had been affected by sihr (magic). Allah ﷻ revealed these verses as protection and as the diagnosis. Seeking refuge in the Lord of daybreak — al-falaq — the splitting of dawn from darkness — is seeking the One who tears apart every form of harm that darkness conceals.
Surah An-Nas — seeking refuge from internal harm
“Say: I seek refuge in the Lord of mankind, the Sovereign of mankind, the God of mankind — from the evil of the retreating whisperer, who whispers into the breasts of mankind — from among jinn and from among people.” (Quran 114)
Where Al-Falaq protects from external harm, An-Nas protects from internal harm — the waswas, the whisper that retreats when you remember Allah ﷻ and returns when you forget. Three names of Allah ﷻ are invoked in rapid succession: the Lord, the Sovereign, the God of mankind. The triple invocation emphasises who you are turning to — your Creator, your King, your only true Deity.
The established practice
Aisha ؓ narrated that every night before sleeping, the Prophet ﷺ would cup his hands, blow into them, recite Al-Ikhlas, Al-Falaq, and An-Nas, and then wipe his hands over his body — beginning with the head and face and whatever he could reach of his front. He would do this three times. (Bukhari · 5017)
He also recited the three Quls after every obligatory prayer (Abu Dawud · 1523, Tirmidhi · 3575 — graded hasan). Morning and evening, the three Quls are part of the established adhkar: recited three times each, they constitute comprehensive daily protection.
Frequently Asked Questions
What are the four Qul Surahs?
The four surahs beginning with “Qul” (Say) are: Al-Kafirun (109), Al-Ikhlas (112), Al-Falaq (113), and An-Nas (114). Together they cover the declaration of tawhid, the rejection of shirk, and comprehensive protection from external harm (Al-Falaq) and internal harm — waswas and whispering (An-Nas).
Why is Surah Al-Ikhlas equal to a third of the Quran?
The Prophet ﷺ confirmed this in sahih hadith (Bukhari · 5013, Muslim · 811). Scholars explain it as: the Quran’s content broadly covers knowledge of Allah ﷻ, knowledge of commands and prohibitions, and knowledge of the afterlife. Surah Al-Ikhlas comprehends the first third entirely — describing the nature and oneness of Allah ﷻ with complete precision in four verses.
When should the Qul Surahs be recited?
After every obligatory prayer (Abu Dawud · 1523); as part of the morning and evening adhkar — three times each; before sleeping — the Prophet ﷺ blew them into his hands and wiped over his body (Bukhari · 5017); and specifically Surah Al-Kafirun before sleep as a disavowal of shirk. These are among the most frequently recommended recitations in the entire Sunnah.
Four short surahs. After every prayer, morning, evening, and before sleep — these are perhaps the most-recommended recitations in the entire Sunnah. The Prophet ﷺ said they are sufficient for everything. Take him at his word.
