ٱسْتَجِيبُوا۟ لِرَبِّكُم مِّن قَبْلِ أَن يَأْتِىَ يَوْمٌۭ لَّا مَرَدَّ لَهُۥ مِنَ ٱللَّهِ ۚ مَا لَكُم مِّن مَّلْجَإٍۢ يَوْمَئِذٍۢ وَمَا لَكُم مِّن نَّكِيرٍۢ
Answer the call of your Lord before there cometh unto you from Allah a Day which there is no averting. Ye have no refuge on that Day, nor have a ye any (power of) refusal.
