"Three Quls" is the common name for Surah Al-Ikhlas, Al-Falaq, and An-Nas — three of the shortest surahs in the Quran, and three of the most frequently recited. If you've looked at any adhkar list, you've already seen them: they show up in the morning and evening routine, after every prayer, and right before sleep. Here's what each one means, why they're grouped together, and why they appear so often.
Why "Three Quls"?
Each surah opens with the word Qul — "Say" — the instruction Allah gives the Prophet ﷺ before the rest of the verse follows. Al-Ikhlas begins Qul huwallahu ahad, Al-Falaq begins Qul a'udhu bi-Rabbil-falaq, and An-Nas begins Qul a'udhu bi-Rabbin-nas. Al-Falaq and An-Nas are also called al-Mu'awwidhatan — "the two surahs of refuge" — since both are built around seeking refuge (a'udhu) in Allah.
What each one says
Surah Al-Ikhlas (112)
قُلْ هُوَ اللَّهُ أَحَدٌ اللَّهُ الصَّمَدُ لَمْ يَلِدْ وَلَمْ يُولَدْ وَلَمْ يَكُنْ لَهُ كُفُوًا أَحَدٌ
Qul huwallahu ahad, Allahus-samad, lam yalid wa lam yulad, wa lam yakun lahu kufuwan ahad.
Say: He is Allah, the One. Allah, the Self-Sufficient Master. He begets not, nor was He begotten, and there is none comparable to Him.
Four short verses stating Allah's oneness in the clearest terms in the Quran. The Prophet ﷺ described this surah as equal to one-third of the Quran — not in length, but in concentrated meaning, since it summarizes the Quran's core teaching about who Allah is.
Source: Sahih al-Bukhari 5015, narrated by Abu Sa'id al-Khudri.
Surah Al-Falaq (113)
قُلْ أَعُوذُ بِرَبِّ الْفَلَقِ مِنْ شَرِّ مَا خَلَقَ وَمِنْ شَرِّ غَاسِقٍ إِذَا وَقَبَ وَمِنْ شَرِّ النَّفَّاثَاتِ فِي الْعُقَدِ وَمِنْ شَرِّ حَاسِدٍ إِذَا حَسَدَ
Qul a'udhu bi-Rabbil-falaq, min sharri ma khalaq, wa min sharri ghasiqin idha waqab, wa min sharrin-naffathati fil-'uqad, wa min sharri hasidin idha hasad.
Say: I seek refuge in the Lord of daybreak, from the evil of what He 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.
Refuge from four categories of harm: general evil in creation, the evil that comes with nightfall, the evil of black magic, and the evil of envy.
Surah An-Nas (114)
قُلْ أَعُوذُ بِرَبِّ النَّاسِ مَلِكِ النَّاسِ إِلٰهِ النَّاسِ مِنْ شَرِّ الْوَسْوَاسِ الْخَنَّاسِ الَّذِي يُوَسْوِسُ فِي صُدُورِ النَّاسِ مِنَ الْجِنَّةِ وَالنَّاسِ
Qul a'udhu bi-Rabbin-nas, Malikin-nas, Ilahin-nas, min sharril-waswasil-khannas, alladhi yuwaswisu fi sudurin-nas, minal-jinnati wan-nas.
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 in the breasts of mankind, from among the jinn and mankind.
Refuge specifically from whispered suggestion — whether it comes from jinn or from people.
Source (on reciting the three together being sufficient): Sunan Abi Dawud 5082 and Jami' at-Tirmidhi 3575, narrated by Abdullah ibn Khubayb — the Prophet ﷺ told him these three "will suffice you against everything."
When these are recited
Morning and evening
Recited three times each as part of the standard morning and evening adhkar, based on the same narration above. The full list, with the rest of the routine, is in our morning adhkar guide.
After every prayer
Recited once each, right after the tasbih that follows the salam.
Source: Sunan Abi Dawud 1523, narrated by Uqbah ibn Amir, graded sahih by Al-Albani — the Prophet ﷺ commanded him to recite them after every prayer. See our after-prayer adhkar guide for the full sequence.
Before sleep
Recited once each, then blown into the cupped hands and wiped over as much of the body as can be reached, repeated three times.
Source: Sahih al-Bukhari 5017, narrated by Aisha. More on the full bedtime routine is in our sleep adhkar guide.
Whenever you want protection or comfort
Nothing in the sources restricts these three surahs to fixed times. They can be recited any time you want a sense of protection — the four occasions above are simply the ones most consistently reported from the Prophet ﷺ, not the only ones permitted.
A practical note
Since these three come up at four separate points in the day — morning, evening, after every prayer, and before sleep — they're one of the easiest things to actually finish consistently, if the moments they belong to aren't lost to a phone screen first. Pray auto-blocks the apps most likely to interrupt these windows, calculated on your device, so the recitation happens before the scroll does.
