And they ask you to hasten the chastisement even though God would never break His promise of sending down the chastisement upon them — and so He sent it down on the day of Badr. And truly a day with your Lord of the days of the Hereafter on account of the severity of the chastisement is like a thousand years of your counting read ta‘uddūna or ya‘uddūna ‘their counting’ in this world.
- 22:4747
وَيَسْتَعْجِلُونَكَ بِالْعَذَابِ وَلَنْ يُخْلِفَ اللَّهُ وَعْدَهُ ۚ وَإِنَّ يَوْمًا عِنْدَ رَبِّكَ كَأَلْفِ سَنَةٍ مِمَّا تَعُدُّونَ
That is how they ask you to hasten the punishment; but God does not go back on His promise. Verily a day with your Lord is equal by your reckoning to a thousand years.
