Surah al‑Kahf - The Jewish Agenda Behind the Three Questions

One of the most remarkable episodes in the early history of Islam concerns the three questions the Makkan Quraysh were instructed to ask the Prophet Muhammad (peace and blessings be upon him and his family) in order to test the authenticity of his claim to prophethood.

According to the classical books of sirah and tafsir, unable to determine for themselves whether Muhammad was a genuine prophet, the Quraysh sent a delegation to the Jewish scholars of Madinah.

The Jews, possessing earlier scriptures and regarding themselves as the custodians of revealed knowledge, advised them to ask about three matters: the youths who disappeared into a cave (ashab al-kahf), the mighty ruler known as Dhu al-Qarnayn, and the nature of the soul (al-ruh). They further declared that if Muhammad answered these questions correctly, he was indeed a prophet; if not, his claim was false.

The coherent strategy behind the questions

More importantly, they were designed to preserve Jewish intellectual authority and to place the Prophet in an impossible position from which, it was hoped, he could not escape. So anti‑prophethood were the Jews, that hoping for anything less was unrealistic. That was their moment to "shine."

The Jews occupied a unique position in Arabia. Unlike the pagan Arabs, they possessed a long scriptural tradition and regarded themselves as heirs to prophetic knowledge. They believed that authentic revelation belonged primarily within their historical and religious inheritance. Consequently, the appearance of an Arab prophet outside the Children of Israel posed a profound theological challenge.

If Muhammad were accepted as a genuine messenger, their exclusive claim to religious authority would necessarily be weakened. It is therefore understandable that they sought objective means of verification. Yet the particular questions they proposed demonstrate that verification was not their only concern. The questions themselves reveal an attempt to define the terms upon which revelation would be judged. From the very outset, their intent was to deliver a decisive blow and to lead the charge.

Each question belonged to a different intellectual sphere, yet all possessed deep significance within Jewish and Christian religious memory. The story of the Sleepers of the Cave circulated primarily within Christian tradition as an account of young believers who remained faithful under persecution and whose miraculous preservation became evidence for bodily resurrection.

Their importance lay in marking the transition from the civilizational-religious legacy of Judaism to that of the newly emerging Christianity, and from the Jewish Jesus to the Christ of Christian faith.

The exact identity of Dhu al-Qarnayn remains uncertain, although some Muslim scholars have identified him with Cyrus the Great, the Persian king whom the Hebrew Bible uniquely describes as God's "anointed" because he liberated the Jews from Babylonian captivity and permitted the rebuilding of the Temple in Jerusalem. If this identification is correct, it is plausible that the Jewish scholars who proposed the question had likewise Cyrus in mind.

As one of the greatest rulers of all time, Cyrus was more than worthy of admiration. The Jews were more than willing to present him, so to speak, as their worldly savior and as God's chosen instrument for the fulfillment of His promise, personally responsible for the liberation of His people from the Babylonian bondage and the chains of exile and for restoring the Jewish civilizational project centered on the Holy Land through the rebuilding of the Temple in Jerusalem.

And finally, the question concerning the soul touched one of the deepest mysteries of theology, one which Jewish tradition itself regarded as belonging ultimately to the knowledge of God alone.

The attempt to lure the Prophet into a trap

Their strategy was particularly subtle. Had the Prophet answered according to Jewish expectations, Christians might accuse him of ignoring or misrepresenting their religious heritage. Had he embraced specifically Christian interpretations, Jewish scholars could reject him as contradicting their understanding of revelation.

If he ventured speculative explanations concerning the soul, he would risk claiming knowledge that belonged only to God. And had he confessed ignorance about the nature of the soul - as was, in reality, the case from a human perspective - the implications would have been immediate and unmistakable.

In every direction lay the possibility of contradiction, controversy, or theological error. The Prophet was meant to be drawn into the unforgiving dialectics of such environments, from which no one emerges unscathed. The questions thus functioned as intellectual traps intended to expose what the Jews expected would be the limitations of a merely human claimant to prophethood.

No matter the response, the Prophet was expected to lose stature, while the prestige and authority of the Jewish scholars would only increase. They were approached as the recognized authorities and were expected to remain so after the Prophet's anticipated fragmented, inconclusive, and inherently less authoritative answers, thereby reaffirming themselves as the sole and definitive arbiters in metaphysical matters.

Be that as it may, whatever the Prophet might have said on his own would have been fraught with difficulty. Any answer that aligned too closely with one religious tradition or system of thought risked placing him and his mission at odds with another. Such an outcome would have been especially detrimental given Islam's universal vocation and its claim to reaffirm the common message of all the prophets.

It should also be recalled that this was a period during which the Prophet, in response to the intensifying persecution of the Quraysh, directed some of his followers to seek refuge in the warm and friendly Christian Abyssinia. Against such a backdrop, answers that appeared to favor one religious community over another could have narrowed opportunities for dialogue and cooperation, closing doors that divine wisdom intended to keep open.

Underlying this Jewish strategy was an effort to retain control over the narrative of revelation itself. Since the questions originated within traditions familiar to Jews and Christians, the implicit assumption was that authentic religious knowledge remained dependent upon the custodians of those earlier traditions. Muhammad would be compelled either to reproduce their accounts, thereby acknowledging and validating their authority, or to expose his ignorance. In either case, they expected to remain the judges of religious truth. As they saw it, the outcome was predetermined: with or without their approval, the Prophet was bound to lose.

From trap to transformation, from narrative to reorientation

While the questions remained localized and narrowly framed, the Qur'anic responses transformed them into universal paradigms. Efforts to reduce truth to subjective or doctrinal premises were countered by its unequivocal affirmation as objective and absolute.

The account of the Sleepers of the Cave illustrates this method beautifully. Whereas Christian tradition devoted considerable attention to the names of the youths, their exact number, the location of the cave, and the precise duration of their miraculous sleep, the Qur'an deliberately passes over most of such details. It explicitly discourages speculative argument about their number and presents the story not as Christian property but as a universal lesson in steadfast belief, youthful courage, trust in God, and divine protection. In the end, truth must prevail, while falsehood collapses.

Historical particulars become secondary to moral truth. The story is liberated from denominational ownership and restored to the inclusive language of revelation.

The same method appears in the account of Dhu al-Qarnayn. The Qur'an intentionally refrains from identifying him by name. Whether he was Cyrus, Alexander, or another historical ruler is left unresolved. What matters instead is his character. He is presented as a ruler endowed with power by God, who governs with justice, protects the weak, restrains corruption, and recognizes that all authority in the final reckoning belongs to Allah.

The emphasis shifts entirely from historical identity to ethical responsibility. In doing so, the Qur'an universalizes political leadership itself. Dhu al-Qarnayn ceases to belong exclusively to Jewish, Persian, or any other memory and becomes an enduring model of righteous governance for all humanity.

The response concerning the soul - given inside Surah al-Isra', though - is perhaps even more profound. Here the Qur'an refuses to satisfy intellectual curiosity altogether. On the contrary, it declares: "The soul is of the affair of my Lord, and you have been given but little knowledge" (al-Isra' 85). In preference to speculating about metaphysical realities, revelation establishes the proper limits of human knowledge.

The answer itself becomes the lesson. True revelation is not obliged to disclose every mystery; it teaches people at once what it needs to know and what it must humbly leave to God. The additional story of Prophet Musa and Khidr in Surah al-Kahf substantially reinforces the hierarchy of knowledge and the ranks of the knowledgeable, at the summit of which stands divine knowledge as the source and conclusive criterion of legitimacy for all knowledge. As it is wisely said, Islam teaches the bounds of knowing - what to seek and what to leave; the bounds of curiosity - what to pursue and what to silence.

The answer: more than an apologetic victory

This demonstrates an important characteristic of the Qur'anic worldview. Revelation does not seek to monopolize sacred history on behalf of one religious community. It presents previous prophets, righteous rulers, and faithful believers as belonging to the common heritage of humankind. Abraham is not exclusively Jewish, Moses not exclusively Israelite, Jesus not exclusively Christian, nor Dhu al-Qarnayn exclusively associated with any single civilization. Their true identity lies in their submission to Almighty God.

Ironically, the very questions intended to undermine the Prophet Muhammad became powerful evidence supporting his prophethood. A merely human author would likely have entered the historical and theological debates that surrounded these figures. The Qur'an consistently refuses to do so.

It exhibits a striking independence from the intellectual expectations of both Jews and Christians. Contrasted with acknowledging and validating existing narratives - or even criticizing them according to the insinuated standards embedded in the questions of the Jews - the Qur'an reconstructs them upon the principles of tawhid (Allah's Oneness), moral responsibility, and universal guidance.

The Jews had hoped to examine revelation in line with norms established by earlier cultures. The Qur'an reversed the direction of the examination. It became previous traditions that were now invited to measure themselves against the criterion of divine revelation. Their historical memories were not rejected, but neither were they allowed to define the final understanding of God's guidance. Conversely, they were themselves reinterpreted and ultimately brought into conformity with the final divine message.
