Muslim 809a concerns memorizing the first ten verses of Al-Kahf and protection from the Dajjal. Muslim 809b records a variant referring to the end of the surah. The report, its location and the verses’ context are distinguished below.
The Hadith's Source
The report from Abu al-Darda is Muslim 809a, in the Book of Prayer—Travellers, under the virtue of Al-Kahf and Ayat al-Kursi. Its wording concerns memorization; the reference is not the Book of Tribulations.
Which Juz Is Surah Al-Kahf In?
Surah Al-Kahf spans juz 15 and 16: it begins in juz 15, continuing directly from Surah Al-Isra (17), and stays within that juz through verse 74; from verse 75 onward it moves into juz 16, where it ends. The first 10 verses referenced in the hadith are in juz 15 — well before the juz-15/16 boundary at verse 74, so there is no ambiguity about which juz they belong to. See our Juz page to see where every surah starts and ends.
The First Ten or the Last Ten? Differences Between Reports
Muslim 809b records the transmission difference: Shu‘ba refers to the end of Al-Kahf, while Hammam refers to its beginning. This explains the first-ten/last-ten distinction. It is separate from reports about reciting the whole surah on Friday.
What Do the First 10 Verses Say?
The first 10 verses of Surah Al-Kahf form the surah's opening: praise of God, the Quran being revealed as a book without deviance, warning wrongdoers and giving good news to those who believe and do righteous deeds, worldly life being a place of trial, and then the opening of the story of the People of the Cave (18:9-10). These verses close with an emphasis on God's oneness and the supplication of the People of the Cave seeking refuge in God ("Our Lord, grant us mercy from Yourself and prepare for us right guidance in our affair") — a supplication that is itself a request for refuge and for staying on the right path. Despite its brevity, this ten-verse section carries both the theme of God's oneness and of seeking refuge together, which makes the protective merit specifically emphasized in the hadith more understandable; this also makes it a valuable starting point both for memorization and for reflection. Its brevity also offers a reasonable, attainable, and motivating goal for those attempting memorization for the first time; someone who completes these ten verses can move on to longer, more ambitious goals with confidence. This small but meaningful achievement adds a concrete sense of progress to a person's relationship with the Quran.
Why Is It Associated with the Dajjal?
The direct basis for the Dajjal connection is the report itself. Al-Kahf’s opening brings together revelation, warning, faith, the transience of worldly life and the young people’s prayer for refuge. Connecting these themes with resistance to deception is a reflection on the passage, not a definitive explanation of why the hadith singles it out.
Is Memorizing Necessary, or Is Reading Alone Enough?
The wording of 809a does not establish that reading alone is identical to memorizing. Reading, studying the meaning and repeating after a reciter can support memorization, but they are distinct activities. Work in manageable sections and check pronunciation against a reliable recitation; learning time varies.
What Is Its Relationship with Friday?
The merit hadith about the first 10 verses of Surah Al-Kahf is a matter independent of the separate reports about reading the surah on Friday; but in practice, many people combine the two, both reading the surah (or a portion of it) on Friday and separately giving attention to the first 10 verses. This combination is not obligatory; it has simply become widespread as a practical habit in daily life. See our article Reading Surah Al-Kahf on Friday for details on the Friday reading practice.
The Lesson Between the People of the Cave and the Trial of the Dajjal
The young people seek refuge in the cave at 18:10; their stance toward belief and pressure is developed further at 18:13-16. The first ten verses introduce the story rather than contain it all. Reading onward connects a ten-verse memorization goal with the larger narrative.
How Can We Make This Report Meaningful?
Those who want to connect a topic that seems abstract and distant, like the trial of the Dajjal, with daily life can also read these verses as a practice of "staying alert against deceptive appearances." Remaining cautious in the face of exaggerated promises and misleading images encountered on social media, in advertising, or in daily relationships is an attitude that aligns with the general principle these verses carry. This interpretation makes the verses meaningful not just as a historical hadith text, but as counsel applicable to present-day life. This perspective makes it easier to keep in mind, while memorizing the verses, not just their sound but also the counsel they carry.
Practical Plan
A practical way for those who want to read these verses regularly: on Friday mornings, you can use the Friday — Selections from Al-Kahf listening routine to listen to the first 10 verses while following their translation, then repeat them weekly with a memorization goal.
Keep the report’s wording about memorization distinct from the useful work of reading and understanding. Start at Al-Kahf verse 1 and explore the surah’s stories and themes. For other reading contexts, see the before-sleep collection and FAQ.
