Signs, prophecies, and predictions in the Qur'an and Sunnah — documented.

What this site is — and is not

This is a reference work, not a sermon. It does not ask the reader to accept any conclusion in advance, and it does not claim that every verse of the Qur'an maps onto a scientific paper. It presents what the primary Islamic sources say, what seventh-century audiences could plausibly have known, what modern knowledge or later history shows, and where the argument is strong, interpretive, or weak. Readers of any faith — or none — should leave better informed about what is actually claimed, and on what basis.

Every entry carries a credibility rating assigned editorially for this site:

Tier 1 · Strong  an authentic source, a clear text, and a well-documented correspondence.
Tier 2 · Interpretive  a reasonable case that depends on how the text is read.
Tier 3 · Contested  a weak or disputed case: a questioned narration, a strained translation, or contested science — included for completeness, and marked plainly.

Working definitions

Sign (or miracle). As used here: a statement in the Qur'an or authentic Hadith argued to align with knowledge about the natural world that was not available in seventh-century Arabia — embryology, oceanography, cosmology, and the like. The Arabic term āyah (“sign”) is the Qur'an's own word for such passages.

Prophecy. A foretelling of a specific event that is judged, on the historical record, to have already occurred — for instance the Roman recovery foretold in Surah ar-Rum.

Prediction. A foretelling of later or still-unfolding developments — including the “signs of the Hour” — whose fulfillment is either recent, partial, or still awaited. The site labels these separately and does not count the unfulfilled as evidence.

A short primer on the sources

The Qur'an is Islam's central scripture, held by Muslims to be the verbatim revelation received by the Prophet Muhammad (peace be upon him) between 610 and 632 CE. It is organized in 114 surahs (chapters) of ayat (verses); citations on this site use the standard surah:ayah numbering and quote the Saheeh International English translation alongside the Arabic.

The Hadith are separately transmitted reports of what the Prophet said and did. Because they were gathered from chains of narrators over generations, Muslim scholars developed a formal grading science: a report may be sahih (authentic), hasan (sound), or da'if (weak), based on the reliability and connectedness of its chain. The two collections regarded as most rigorous are Sahih al-Bukhari and Sahih Muslim. This site cites collection and number for every hadith, reports its grading, and treats weak narrations as weak — they appear, if at all, at Tier 3.

Two misconceptions, addressed evenhandedly

“These are all retrofitted readings.” The skeptic's concern is real and this site takes it seriously: it is easy to read modern discoveries back into old, ambiguous words, and some popular claims do exactly that. That is why each entry states the counterargument, why translation disputes are flagged rather than hidden, and why a large share of the catalog sits at Tier 2 or 3. But the concern does not settle every case: some passages make specific, checkable statements — a defeated empire's recovery within a stated window, a body preserved “as a sign” — where the retrofitting objection has to work harder, and the entries lay out both sides.

“Every verse anticipates modern science.” The enthusiast's version overreaches in the other direction. The Qur'an describes itself as guidance, not a science textbook; classical commentators read most of these passages theologically, and forcing each one onto a twenty-first-century discovery cheapens the argument and collapses under scrutiny. The tiering exists precisely to resist that: where a claim is weak, this site says so.
