﴿ وَيَوْمَ يَحْشُرُهُمْ كَأَن لَّمْ يَلْبَثُوٓا۟ إِلَّا سَاعَةًۭ مِّنَ ٱلنَّهَارِ يَتَعَارَفُونَ بَيْنَهُمْ ۚ قَدْ خَسِرَ ٱلَّذِينَ كَذَّبُوا۟ بِلِقَآءِ ٱللَّهِ وَمَا كَانُوا۟ مُهْتَدِينَ ﴾

“And on the Day when He shall gather them [unto Himself, it will seem to them] as if they had not tarried [on earth] longer than an hour of a day, knowing one another; [and] lost indeed will be they who [in their lifetime] considered it a lie that they were destined to meet God, and [thus] failed to find the right' way.”

Commentary In verse 45, it was said: يَتَعَارَ‌فُونَ بَيْنَهُمْ (they will recognize each other), that is, when the dead will be raised from their graves, they will recognize each other as if not much time had passed when they met last. Imam al-Baghawi said: This recognition will be possible during the early stage. Later, when the horrendous happenings of the Qiyamah, the Day of Doom, will unfold, this ability to recognize each other will stand disabled. According to some other narrations, the ability to recognize each other will, though, still remain, but such will be the awe of the situation that they will be unable to say anything. (Mazhari)
