What does the Quran mean by 'a day is like a thousand years'?

The Quran uses this expression to illustrate the vast difference between divine and human time. It is not a literal measurement but a way to convey Allah's patience, the grand scale of His plan, and His existence beyond the limitations of human time. It often serves as a response to those who impatiently demand immediate divine intervention or punishment.

Are there other similar comparisons of time in the Quran?

Yes, in Surah Al-Ma'arij (70:4), the Quran mentions a day being equivalent to 'fifty thousand years.' Scholars interpret this as referring to a different divine process, such as the duration of the Day of Judgment or the time it takes for angels to ascend to Allah, highlighting that different divine activities have different temporal scales.

How do scholars explain the difference between a day being 1,000 years and 50,000 years in the Quran?

Scholars offer several reconciliations. Some suggest the verses refer to different 'days': one for divine administration (1,000 years) and another for the Day of Judgment (50,000 years). Others propose that the experience of the Day of Judgment will vary, feeling longer for disbelievers than for believers. Another view is that they describe different divine actions, each with its own unique time scale.
