The Day with Allah in the Holy Quran

﴿وَيَسۡتَعۡجِلُونَكَ بِٱلۡعَذَابِ وَلَن يُخۡلِفَ ٱللَّهُ وَعۡدَهُۥۚ وَإِنَّ يَوۡمًا عِندَ رَبِّكَ كَأَلۡفِ سَنَةٖ مِّمَّا تَعُدُّونَ ﴾ [Al-Ḥajj: 47]

(47) And they urge you to hasten the punishment. But Allah will never fail in His promise. And indeed, a day with your Lord is like a thousand years of those which you count.
