سورة الحج

وَيَسْتَعْجِلُونَكَ بِالْعَذَابِ وَلَنْ يُخْلِفَ اللَّهُ وَعْدَهُ ۚ وَإِنَّ يَوْمًا عِنْدَ رَبِّكَ كَأَلْفِ سَنَةٍ مِمَّا تَعُدُّونَ ﴿٤٧﴾

Surah al-Hajj

47. And they challenge you to hurry up the punishment. And Allah will never break His promise. But a day with your Lord is as a thousand years of your count.
