Al A’raf Ayah 46

وَبَيْنَهُمَا حِجَابٌ‌ۚ وَعَلَى ٱلْأَعْرَافِ رِجَالٌ يَعْرِفُونَ كُلاَّۢ بِسِيمَـٰهُمْ‌ۚ وَنَادَوْاْ أَصْحَـٰبَ ٱلْجَنَّةِ أَن سَلَـٰمٌ عَلَيْكُمْ‌ۚ لَمْ يَدْخُلُوهَا وَهُمْ يَطْمَعُونَ ٤٦ There will be a barrier between Paradise and Hell. And on the heights ?of that barrier? will be people who will recognize ?the residents of? both by their appearance. They will call out to the residents of Paradise, “Peace be upon you!” They will have not yet entered Paradise, but eagerly hope to.
