Qur'an 39:55 · Az-Zumar

وَٱتَّبِعُوٓا۟ أَحْسَنَ مَآ أُنزِلَ إِلَيْكُم مِّن رَّبِّكُم مِّن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ بَغْتَةًۭ وَأَنتُمْ لَا تَشْعُرُونَ

(55) And follow the best of what was revealed to you from your Lord [i.e., the Qur’ān] before the punishment comes upon you suddenly while you do not perceive,
