Quran 22:47 from Surah Al-Hajj on Divine Marvels.
وَيَسۡتَعۡجِلُونَكَ بِٱلۡعَذَابِ وَلَن يُخۡلِفَ ٱللَّهُ وَعۡدَهُۥۚ وَإِنَّ يَوۡمًا عِندَ رَبِّكَ كَأَلۡفِ سَنَةٖ مِّمَّا تَعُدُّونَ
English translation: And they ask you to hasten the punishment But never will Allah fail Allah fail (in) His Promise And indeed a day with your Lord (is) like a thousand year(s) of what you count
Transliteration: wayasta'jilunaka bil-'adhabi walan yukh'lifa al-lahu wa'dahu wa-inna yawman inda rabbika ka-alfi sanatin mimma ta'udduna
