Al-Hajj 22:47

وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ وَلَن يُخْلِفَ ٱللَّهُ وَعْدَهُۥ ۚ وَإِنَّ يَوْمًا عِندَ رَبِّكَ كَأَلْفِ سَنَةٍ مِّمَّا تَعُدُّونَ

Wayastaʿjilūnaka bil-ʿadhābi walan yukh'lifa l-lahu waʿdahu wa-inna yawman ʿinda rabbika ka-alfi sanatin mimmā taʿuddūna

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