وَبَيْنَهُمَا حِجَابٌۭ ۚ وَعَلَى ٱلْأَعْرَافِ رِجَالٌۭ يَعْرِفُونَ كُلًّۢا بِسِيمَىٰهُمْ ۚ وَنَادَوْا۟ أَصْحَٰبَ ٱلْجَنَّةِ أَن سَلَٰمٌ عَلَيْكُمْ ۚ لَمْ يَدْخُلُوهَا وَهُمْ يَطْمَعُونَ
Between them is a veil. And on the Heights are men who know them all by their marks. And they call unto the dwellers of the Garden: Peace be unto you! They enter it not although they hope (to enter).
