This entry examines an authentic and widely reported sign of the Hour — that the sun will one day rise from the west — and the modern claim that connects it to a geomagnetic pole reversal, the periodic flipping of the Earth's magnetic field. The narration is strong; the scientific parallel is real but must be stated with care.

لاَ تَقُومُ السَّاعَةُ حَتَّى تَطْلُعَ الشَّمْسُ مِنْ مَغْرِبِهَا فَإِذَا طَلَعَتْ وَرَآهَا النَّاسُ آمَنُوا أَجْمَعُونَ

What was understood in the seventh century
Among the major signs preceding the Day of Judgment named in authentic hadith, the sun rising from its place of setting is one of the most frequently cited. The Prophet Muhammad (peace be upon him) is reported in narrations agreed upon by al-Bukhari and Muslim to have said that the Hour would not come until the sun rose from the west, and that when people witnessed it, faith would no longer benefit those who had not already believed.
To a seventh-century audience the sign meant a plain and decisive reversal of the daily order of nature: the sun, which rises in the east every morning without exception, appearing instead in the opposite quarter of the sky. It was understood as a visible, universal, and unmistakable event.
The fulfillment record
The modern parallel draws on a well-established fact of geophysics. The Earth's magnetic field is not fixed: its polarity reverses at irregular intervals, so that magnetic north and magnetic south trade places. These reversals are recorded in the magnetic stripes of the ocean floor and in volcanic rock; the most recent complete reversal took place roughly 780,000 years ago, and many have occurred over the planet's history.
There is a genuine sense in which such a reversal supports the language of the sign. Direction, as measured by a magnetic compass, is defined by the field itself. After a completed pole reversal, a compass needle that points north today would point south, and every compass bearing would invert with it — so relative to that compass, the sun would then rise from what the instrument reads as the west. On the definition of west that a navigator's compass provides, the sun rising 'from the west' becomes a literal, physically coherent statement of what a reversed field would produce.
Considerations and counterpoints
The parallel is real, but its limits should be stated plainly, and they are why this entry sits at Tier 3. A geomagnetic reversal changes only the magnetic field. It does not alter the Earth's rotation, and the sun's actual rising point on the horizon — its geographic east, fixed by the direction the planet spins — would not move at all. The reversal reinterprets 'west' as a compass direction rather than the ordinary geographic one that the original statement most naturally carries.
Two further differences matter. Real reversals are gradual, unfolding over centuries to millennia, and are imperceptible to the unaided eye — one would need instruments to notice the field changing at all. The hadith, by contrast, describes a sudden, sky-wide event that everyone sees at once and that halts ordinary life in its tracks. In Islamic theology the sign is understood as a supernatural occurrence at the end of time, not a slow natural drift. For these reasons the magnetic-reversal reading is best presented as an evocative and partly valid parallel — science does support 'the sun rising from the magnetic west' once directions are read from a compass — rather than as a demonstrated fulfillment of the sign as it was originally meant.
Credibility rating: Tier 3 · Contested — The hadith is authentic and agreed upon, but the geomagnetic-reversal correspondence only holds if 'west' is redefined magnetically rather than geographically, and the gradual, imperceptible nature of real reversals does not match the sudden, universally witnessed sign described.
