Surah Yunus — Ayah 45 (10:45)
وَيَوۡمَ يَحۡشُرُهُمۡ كَأَن لَّمۡ يَلۡبَثُوٓاْ إِلَّا سَاعَةٗ مِّنَ ٱلنَّهَارِ يَتَعَارَفُونَ بَيۡنَهُمۡۚ قَدۡ خَسِرَ ٱلَّذِينَ كَذَّبُواْ بِلِقَآءِ ٱللَّهِ وَمَا كَانُواْ مُهۡتَدِينَ ٤٥
English translation (Saheeh International)
And on the Day when He will gather them, [it will be] as if they had not remained [in the world] but an hour of the day, [and] they will know each other. Those will have lost who denied the meeting with Allāh and were not guided.
Brief commentary
On the day that Allah gathers people on the Day of Judgement, to bring them to account, it will be as if they had lived on earth and then waited after death for the Day of Judgement for only an hour, and no more. They will recognise each other on that day, but then their acquaintances will be cut off from them because of the intensity of the terrors they witness on the Day of Judgement. The losers will be those who rejected the meeting with their Lord on the Day of Judgement and who did not believe in the day or resurrection so that they could safeguard themselves from loss.
