The Quran's approach to conversion — or more precisely, reversion, since Islamic theology holds that every person is born in a state of fitra (natural disposition toward God) — centers on invitation, monotheism, and voluntary submission. It's worth noting upfront that the Arabic word Islam itself means "submission," and becoming Muslim means submitting oneself to the one God, Allah.

One of the clearest conversion-related passages is Quran 21:108, where the Prophet Muhammad is instructed to declare the oneness of God and invite people to submit Quran 21:108. The verse is direct and unadorned: it reduces the entire invitation to a single theological claim — your god is one God. Scholars like Fazlur Rahman (d. 1988) have argued this verse encapsulates the Quran's minimalist creedal requirement for entry into Islam.

Quran 42:15 adds important texture to this picture Quran 42:15. The Prophet is told to invite to the religion, remain steadfast, and refuse to follow the inclinations of others — but crucially, the verse also emphasizes justice and acknowledges that each community is accountable for its own deeds. The phrase "there is no need for argument between us and you" is significant: it suggests that the invitation is offered without coercion or theological browbeating. Classical commentators like al-Tabari (d. 923 CE) read this verse as establishing a posture of confident, peaceful da'wa (invitation).

The hadith tradition fleshes out what conversion looked like in practice. The story of Abu Dhar al-Ghifari, preserved in Sahih al-Bukhari, is one of the most vivid early conversion narratives Sahih al Bukhari 3522. Abu Dhar traveled independently to Mecca, sought out the Prophet, and upon hearing the principles of Islam, embraced the faith immediately. What's striking is that the Prophet initially advised him to keep his conversion secret for safety — yet Abu Dhar publicly declared his faith anyway and was beaten for it. This account illustrates that early conversion was a deeply personal, voluntary act, sometimes carried out at personal risk, rather than a socially coerced one.

There is genuine scholarly disagreement about whether the Quran permits or prohibits forced conversion. Most mainstream Muslim scholars, citing Quran 2:256 ("there is no compulsion in religion" — though this verse wasn't among the retrieved passages, it's the most cited on this topic), argue conversion must be voluntary. However, some medieval jurists interpreted certain military verses as permitting pressure on non-Muslims. Contemporary scholars like Khaled Abou El Fadl strongly reject coercive readings.

The Qur'an frames conversion as responding to a clear proclamation of God’s oneness and an invitation to submit: “your god is but one God; so will you be Muslims [in submission to Him]?” Quran 21:108.

It instructs the Prophet to invite people, to stand firm, to do justice, and to avoid fruitless argument—stressing that each person is responsible for their own deeds and that God will gather everyone for final judgment Quran 42:15.

In practice, early Muslims sometimes accepted Islam immediately upon hearing its core principles; Abu Dharr al-Ghifari’s story records him asking the Prophet to present Islam’s principles, embracing them at once, and publicly bearing witness to faith despite opposition Sahih al Bukhari 3522.

Interpretations vary on tone and method, but these texts emphasize invitation, clarity about monotheism, moral integrity, and personal accountability before God Quran 42:15Quran 21:108.
