وَيَومَ يَحشُرُهُم كَأَن لَم يَلبَثوا إِلّا ساعَةً مِنَ النَّهارِ يَتَعارَفونَ بَينَهُم ۚ قَد خَسِرَ الَّذينَ كَذَّبوا بِلِقاءِ اللَّهِ وَما كانوا مُهتَدينَ
On the Day when He gathers them all, it will seem as if they had only lingered for an hour of a day, familiarizing themselves with each other. Those who denied the encounter with God and were not guided will be the ones to suffer loss.
