Qur'an 7:46

وَبَيْنَهُمَا حِجَابٌ ۚ وَعَلَى ٱلْأَعْرَافِ رِجَالٌ يَعْرِفُونَ كُلًّۢا بِسِيمَىٰهُمْ ۚ وَنَادَوْا۟ أَصْحَـٰبَ ٱلْجَنَّةِ أَن سَلَـٰمٌ عَلَيْكُمْ ۚ لَمْ يَدْخُلُوهَا وَهُمْ يَطْمَعُونَ

“And between them will be a partition [i.e., wall], and on [its] elevations are men who recognize all by their mark. And they call out to the companions of Paradise, "Peace be upon you." They have not [yet] entered it, but they long intensely.”
