وَيَقُولُونَ مَتَىٰ هَٰذَا الْوَعْدُ إِنْ كُنْتُمْ صَادِقِينَ ٣٨
They say: "When will this promise come to pass, if ye are telling the truth?"
21:39
لَوْ يَعْلَمُ الَّذِينَ كَفَرُوا حِينَ لَا يَكُفُّونَ عَنْ وُجُوهِهِمُ النَّارَ وَلَا عَنْ ظُهُورِهِمْ وَلَا هُمْ يُنْصَرُونَ ٣٩
If only the Unbelievers knew (the time) when they will not be able to ward off the fire from their faces, nor yet from their backs, and (when) no help can reach them!
21:40
بَلْ تَأْتِيهِمْ بَغْتَةً فَتَبْهَتُهُمْ فَلَا يَسْتَطِيعُونَ رَدَّهَا وَلَا هُمْ يُنْظَرُونَ ٤٠
Nay, it may come to them all of a sudden and confound them: no power will they have then to avert it, nor will they (then) get respite.
21:41
وَلَقَدِ اسْتُهْزِئَ بِرُسُلٍ مِنْ قَبْلِكَ فَحَاقَ بِالَّذِينَ سَخِرُوا مِنْهُمْ مَا كَانُوا بِهِ يَسْتَهْزِئُونَ ٤١
Mocked were (many) messenger before thee; But their scoffers were hemmed in by the thing that they mocked.
21:42
قُلْ مَنْ يَكْلَؤُكُمْ بِاللَّيْلِ وَالنَّهَارِ مِنَ الرَّحْمَٰنِ ۗ بَلْ هُمْ عَنْ ذِكْرِ رَبِّهِمْ مُعْرِضُونَ ٤٢
Say: "Who can keep you safe by night and by day from (the Wrath of) (Allah) Most Gracious?" Yet they turn away from the mention of their Lord.
