﴿ ٱسْتَجِيبُوا۟ لِرَبِّكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌۭ لَّا مَرَدَّ لَهُۥ مِنَ ٱللَّهِ ۚ مَا لَكُم مِّن مَّلْجَإٍۢ يَوْمَئِذٍۢ وَمَا لَكُم مِّن نَّكِيرٍۢ ﴾

“[Hence, O men,] respond to your Sustainer before there comes, at God’s behest, a Day on which there will be no turning back: [for] on that Day you will have no place of refuge, and neither will you be able to deny aught [of the wrong that you have done].”
