وَإِذَا قِيلَ إِنَّ وَعْدَ اللَّهِ حَقٌّ وَالسَّاعَةُ لَا رَيْبَ فِيهَا قُلْتُم مَّا نَدْرِي مَا السَّاعَةُ إِن نَّظُنُّ إِلَّا ظَنًّا وَمَا نَحْنُ بِمُسْتَيْقِنِينَ
[45:32]
And when it was said, Surely the promise of Allah is true and as for the hour, there is no doubt about it, you said: We do not know what the hour is; we do not think (that it will come to pass) save a passing thought, and we are not at all sure.
"And when it was said that the promise of Allah was true, and that the Hour- there was no doubt about its (coming), ye used to say, 'We know not what is the hour: we only think it is an idea, and we have no firm assurance.'"
And when it was said: Lo! Allah's promise is the truth, and there is no doubt of the Hour's coming, ye said: We know not what the Hour is. We deem it naught but a conjecture, and we are by no means convinced.
