وَأَنِيبُوا إِلَى رَبِّكُمْ وَأَسْلِمُوا لَهُ مِن قَبْلِ أَن يَأْتِيَكُمُ الْعَذَابُ ثُمَّ لَا تُنصَرُونَ
[39:54]
And return to your Lord time after time and submit to Him before there comes to you the punishment, then you shall not be helped.
"Turn ye to our Lord (in repentance) and bow to His (Will), before the Penalty comes on you: after that ye shall not be helped.
Turn unto your Lord repentant, and surrender unto Him, before there come unto you the doom, when ye cannot be helped.
