(Al-Ahraf) 7 : 46
وَبَيْنَهُمَا حِجَابٌ ۚ وَعَلَى الْأَعْرَافِ رِجَالٌ يَعْرِفُونَ كُلًّا بِسِيمَاهُمْ ۚ وَنَادَوْا أَصْحَابَ الْجَنَّةِ أَنْ سَلَامٌ عَلَيْكُمْ ۚ لَمْ يَدْخُلُوهَا وَهُمْ يَطْمَعُونَ
In Between them there will be a wall, and upon its top, there will be men who recognize everyone by their features, and they will call out to the inhabitants of Paradise: "Indeed, Peace be upon you!"; they have not entered in It even though they are wishing.
