Surah Ghafir — Ayah 59 (40:59)
إِنَّ ٱلسَّاعَةَ لَأٓتِيَةٞ لَّا رَيۡبَ فِيهَا وَلَٰكِنَّ أَكۡثَرَ ٱلنَّاسِ لَا يُؤۡمِنُونَ ٥٩
English translation (Saheeh International)
Indeed, the Hour is coming - no doubt about it - but most of the people do not believe.
Brief commentary
The Hour in which Allah will raise the dead for reckoning and reward is definitely coming, without doubt, but most people do not believe it is coming. That is why they do not prepare for it through faith and good actions.
