When it is proclaimed that God’s promise is the truth and that the Hour (of Judgment) is inevitable, you said, “We do not know what the Hour is! We are full of conjecture about it; we are not certain.”
وَإِذا قيلَ إِنَّ وَعدَ اللَّهِ حَقٌّ وَالسّاعَةُ لا رَيبَ فيها قُلتُم ما نَدرى مَا السّاعَةُ إِن نَظُنُّ إِلّا ظَنًّا وَما نَحنُ بِمُستَيقِنينَ
wa izaa qeela inna wa’dallaahi haqqunw was Saa’atu laa raiba feehaa qultum maa nadree mas Saa’atu in nazunnu illaa zannanw wa maa nahnu bimustaiqineen
