The Quran

فَاصبِر كَما صَبَرَ أُولُو العَزمِ مِنَ الرُّسُلِ وَلا تَستَعجِل لَهُم ۚ كَأَنَّهُم يَومَ يَرَونَ ما يوعَدونَ لَم يَلبَثوا إِلّا ساعَةً مِن نَهارٍ ۚ بَلاغٌ ۚ فَهَل يُهلَكُ إِلَّا القَومُ الفاسِقونَ

Muhammad Asad

REMAIN, then, [O believer,] patient in adversity, just as all of the apostles, endowed with firmness of heart, bore themselves with patience. And do not ask for a speedy doom of those [who still deny the truth]: on the Day when they see [the fulfilment of] what they were promised,¹ [it will seem to them] as though they had dwelt [on earth] no longer than one hour of [an earthly] day!² [This is Our] message. Will, then, any be [really] destroyed save iniquitous folk?³

I.e., the reality of life after death.
In this parabolic manner the Qur'an points to the illusory concept of "time" as experienced by the human mind - a concept which has no bearing on the ultimate reality to be unfolded in the hereafter.
Cf. the last sentence of 6:47 and the corresponding note 37.
