Like an hour of a day

اعوذ بالله من الشيطن الرجيم

Surah 10. Yunus, Verse 45:

وَيَوْمَ يَحْشُرُهُمْ كَأَن لَّمْ يَلْبَثُوا إِلَّا سَاعَةً مِّنَ النَّهَارِ يَتَعَارَفُونَ بَيْنَهُمْ قَدْ خَسِرَ الَّذِينَ كَذَّبُوا بِلِقَاءِ اللَّهِ وَمَا كَانُوا مُهْتَدِينَ

Translation:

And on the Day when He shall gather (resurrect) them together, (it will be) as if they had not stayed (in the life of this world and graves, etc.) but an hour of a day. They will recognise each other. Ruined indeed will be those who denied the meeting with Allah, and were not guided.
