Al Hajj Ayah 47

وَيَسْتَعْجِلُونَكَ بِٱلْعَذَابِ وَلَن يُخْلِفَ ٱللَّهُ وَعْدَهُۥ‌ۚ وَإِنَّ يَوْمًا عِندَ رَبِّكَ كَأَلْفِ سَنَةٍ مِّمَّا تَعُدُّونَ ٤٧ They challenge you ?O Prophet? to hasten the torment. And Allah will never fail in His promise. But a day with your Lord is indeed like a thousand years by your counting.
