Az-Zumar 39:54

وَأَنِيبُوٓا۟ إِلَىٰ رَبِّكُمْ وَأَسْلِمُوا۟ لَهُۥ مِن قَبْلِ أَن يَأْتِيَكُمُ ٱلْعَذَابُ ثُمَّ لَا تُنصَرُونَ

Wa-anībū ilā rabbikum wa-aslimū lahu min qabli an yatiyakumu l-ʿadhābu thumma lā tunṣarūna

And return [in repentance] to your Lord and submit to Him before the punishment comes upon you; then you will not be helped.
