The Prophet ﷺ said: I hope my community will not fail to maintain their position in the sight of their Lord if He delays them half a day. Sa'd was asked: How long is half a day? He said: It is five hundred years.
أَنَّ النَّبِيَّ ﷺ قَالَ إِنِّي لأَرْجُو أَنْ لاَ تُعْجِزَ أُمَّتِي عِنْدَ رَبِّهَا أَنْ يُؤَخِّرَهُمْ نِصْفَ يَوْمٍ قِيلَ لِسَعْدٍ وَكَمْ نِصْفُ يَوْمٍ قَالَ خَمْسُمِائَةِ سَنَةٍ
