Al-Kahf — First & Last 10 — Protection from the Dajjal
سُورَةُ الكَهۡفِ

Surah
Al-Kahf (18)
Period
Makkan
Juz
15–16
The Prophet ﷺ singled out the opening and closing verses of Sūrat al-Kahf as a shield against the greatest trial that will ever face mankind — the fitnah of the Dajjāl. Whoever commits these ten verses to memory carries a protection the Prophet ﷺ promised by name. That is why this guide gathers them together: the first ten, which establish the truth of the Book and the parable of the believing youths, and the last ten, which expose the loss of those who reject their Lord and close with the surah's defining call to sincere, monotheistic action.
The full sūrah weaves four stories — the People of the Cave, the man of the two gardens, Mūsā and al-Khiḍr, and Dhul-Qarnayn — each a lesson in a different trial: faith, wealth, knowledge, and power. This guide does not cover those middle narratives; it focuses only on the protective opening and closing that the Sunnah highlights.

Before you begin
Start with sincerity — ask Allah to make this easy for you and to let what you learn benefit you. A short dua to begin with:
رَبِّ زِدْنِي عِلْمًا
Rabbi zidni ‘ilma — “My Lord, increase me in knowledge.” (Qur'an 20:114)

Core message
The surah opens with praise to Allah for sending down a Book with no ʿiwaj — no deviance or crookedness — perfectly straight, to warn of severe punishment and to give the believers glad tidings of an everlasting good reward (vv.1–3). It then issues a pointed warning to those who claim Allah has taken a son (vv.4–5), consoles the Prophet ﷺ over those who reject the message (v.6), and frames this worldly life as an adornment by which we are tested (vv.7–8). The section closes by introducing the youths of the cave who fled to their Lord seeking mercy and right guidance (vv.9–10).
1–3
ٱلْحَمْدُ لِلَّهِ ٱلَّذِىٓ أَنزَلَ عَلَىٰ عَبْدِهِ ٱلْكِتَٰبَ وَلَمْ يَجْعَل لَّهُۥ عِوَجَا ۜ•قَيِّمًۭا لِّيُنذِرَ بَأْسًۭا شَدِيدًۭا مِّن لَّدُنْهُ وَيُبَشِّرَ ٱلْمُؤْمِنِينَ ٱلَّذِينَ يَعْمَلُونَ ٱلصَّٰلِحَٰتِ أَنَّ لَهُمْ أَجْرًا حَسَنًۭا•مَّٰكِثِينَ فِيهِ أَبَدًۭا
[All] praise is [due] to Allah, who has sent down upon His Servant the Book and has not made therein any deviance. [He has made it] straight, to warn of severe punishment from Him and to give good tidings to the believers who do righteous deeds that they will have a good reward In which they will remain forever
4–6
وَيُنذِرَ ٱلَّذِينَ قَالُوا۟ ٱتَّخَذَ ٱللَّهُ وَلَدًۭا•مَّا لَهُم بِهِۦ مِنْ عِلْمٍۢ وَلَا لِءَابَآئِهِمْ ۚ كَبُرَتْ كَلِمَةًۭ تَخْرُجُ مِنْ أَفْوَٰهِهِمْ ۚ إِن يَقُولُونَ إِلَّا كَذِبًۭا•فَلَعَلَّكَ بَٰخِعٌۭ نَّفْسَكَ عَلَىٰٓ ءَاثَٰرِهِمْ إِن لَّمْ يُؤْمِنُوا۟ بِهَٰذَا ٱلْحَدِيثِ أَسَفًا
And to warn those who say, "Allah has taken a son." They have no knowledge of it, nor had their fathers. Grave is the word that comes out of their mouths; they speak not except a lie. Then perhaps you would kill yourself through grief over them, [O Muhammad], if they do not believe in this message, [and] out of sorrow.
7–8
إِنَّا جَعَلْنَا مَا عَلَى ٱلْأَرْضِ زِينَةًۭ لَّهَا لِنَبْلُوَهُمْ أَيُّهُمْ أَحْسَنُ عَمَلًۭا•وَإِنَّا لَجَٰعِلُونَ مَا عَلَيْهَا صَعِيدًۭا جُرُزًا
Indeed, We have made that which is on the earth adornment for it that We may test them [as to] which of them is best in deed. And indeed, We will make that which is upon it [into] a barren ground.
9–10
أَمْ حَسِبْتَ أَنَّ أَصْحَٰبَ ٱلْكَهْفِ وَٱلرَّقِيمِ كَانُوا۟ مِنْ ءَايَٰتِنَا عَجَبًا•إِذْ أَوَى ٱلْفِتْيَةُ إِلَى ٱلْكَهْفِ فَقَالُوا۟ رَبَّنَآ ءَاتِنَا مِن لَّدُنكَ رَحْمَةًۭ وَهَيِّئْ لَنَا مِنْ أَمْرِنَا رَشَدًۭا
Or have you thought that the companions of the cave and the inscription were, among Our signs, a wonder? [Mention] when the youths retreated to the cave and said, "Our Lord, grant us from Yourself mercy and prepare for us from our affair right guidance."
Memory hook — straight Book, then the fleeing youths
Anchor the first ten on two images. First, the Book that is straight: al-ḥamdu lillāh (v.1) → lam yajʿal lahu ʿiwajā (no crookedness) → qayyimā (straight, v.2). Second, the youths who fled: the section ends on their duʿāʾ in v.10 — rabbanā ātinā min ladunka raḥmah (“Our Lord, grant us mercy from Yourself”). Straight Book in, fleeing youths out — that is the arc of the ten.
Why these ten guard against the Dajjāl
Scholars note that the opening ten arm the heart against exactly the Dajjāl's weapons: they affirm tawḥīd against the lie of a “son” (vv.4–5), expose the world as mere zīnah (adornment) and a test (vv.7–8), and hold up the People of the Cave — youths who abandoned everything for their faith — as the model of holding firm under trial (vv.9–10). A heart grounded in these truths is not easily deceived.
The People of the Cave — Aṣḥāb al-Kahf
Verse 9 names aṣḥāb al-kahf wa-r-raqīm — the companions of the cave and the inscription — and v.10 captures the moment they retreated into it. Their story (told in full later in the surah) is the first of the surah's four trials: the trial of faith, met by young believers who chose their Lord over their people and were sheltered and preserved by Him.

For protection from the Dajjāl
The Prophet ﷺ tied protection from the Dajjāl directly to memorizing ten verses of Sūrat al-Kahf — the beginning in one wording, the end in another. Both are authentic, so memorizing either set earns the promise, and memorizing both is greater. Beyond memorization, reciting the whole sūrah on Friday brings the light that shines between the two Fridays. Treat these twenty verses as the core to lock into the heart, then build outward toward the full sūrah.
Memorize the first or last ten — the Dajjāl shield
Verses 1–10 or 101–110 · following the Prophetic promise
The narration of Sahih Muslim mentions ten verses from the beginning; another wording mentions ten from the end. Memorizing either set fulfils the promise of protection from the Dajjāl — memorizing both is best.
Begin with whichever set is easier to retain, review it daily until it is firm, then add the second. Aim to recall both the Arabic and the meaning so the verses actually shape the heart against trial.
Many keep the first ten as part of their regular adhkār, recalling that the opening verses end on the duʿāʾ of the youths (v.10) — a fitting plea to carry into one's own day.
Recite the full sūrah on Friday — the light
Jumuʿah practice · for the light between the two Fridays
The reward of the light shining between the two Fridays is tied to reciting the whole sūrah on the day of Jumuʿah — the window runs from Thursday sunset (Maghrib) through Friday's Maghrib, per the scholars.
If reading the full 110 verses at once is difficult, split it across the day; the goal is to complete the sūrah within the Friday window. The twenty protective verses memorized in card A naturally anchor the start and the finish of that recitation.
Natural stopping points
v.3
mākithīna fīhi abadā — end of the opening praise: the believers' reward that lasts forever. A clean close to the first three verses.
v.10
wa hayyiʾ lanā min amrinā rashadā — the duʿāʾ of the youths of the cave and the end of the first protective ten. A complete, beautiful landing.
v.108
lā yabghūna ʿanhā ḥiwalā — the people of Firdaws abide forever, desiring no transfer. A natural pause before the final two verses.
v.110
wa lā yushrik bi-ʿibādati rabbihi aḥadā — the surah's climactic final word: sincere righteous action and pure tawḥīd. The summit of the whole sūrah.
