وَإِذَا قِيلَ إِنَّ وَعۡدَ ٱللَّهِ حَقّٞ وَٱلسَّاعَةُ لَا رَيۡبَ فِيهَا قُلۡتُم مَّا نَدۡرِي مَا ٱلسَّاعَةُ إِن نَّظُنُّ إِلَّا ظَنّٗا وَمَا نَحۡنُ بِمُسۡتَيۡقِنِينَ
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.
