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
Turn to your Lord. Submit to Him before the punishment overtakes you and you can no longer be helped.
"And turn in repentance and in obedience with true Faith (Islâmic Monotheism) to your Lord and submit to Him (in Islâm) before the torment comes upon you, (and) then you will not be helped.
