Surah Al-A'raf, ayah 46

وَبَيۡنَهُمَا حِجَابٞۚ وَعَلَى ٱلۡأَعۡرَافِ رِجَالٞ يَعۡرِفُونَ كُلَّۢا بِسِيمَىٰهُمۡۚ وَنَادَوۡاْ أَصۡحَٰبَ ٱلۡجَنَّةِ أَن سَلَٰمٌ عَلَيۡكُمۡۚ لَمۡ يَدۡخُلُوهَا وَهُمۡ يَطۡمَعُونَ ٤٦

Wabaynahumā hijābun wa'alal-a'rāfi rijālun ya'rifūna kullā bisīmāhum wanādaw ashābal-jannati an salāmun 'alaykum lam yadkhulūhā wahum yatma'ūn
