[Machine] I heard Abdullah ibn Amr saying, "Indeed, the mentioned wall by Allah the Exalted in the Quran, 'Then it is struck for them a barrier which has a gate in it. Within it is mercy, but on the outside of it is torment' [Surah Al-Hadid: 13] is the wall of the eastern side, inside of which is the mosque and what follows it, and on the outside of it is the Valley of Hellfire."  

سَمِعْتُ عَبْدَ اللَّهِ بْنَ عَمْرٍو يَقُولُ إِنَّ السُّورَ الَّذِي ذَكَرَهُ اللَّهُ تَعَالَى فِي الْقُرْآنِ {فَضُرِبَ بَيْنَهُمْ بِسُوَرٍ لَهُ بَابٌ بَاطِنُهُ فِيهِ الرَّحْمَةُ وَظَاهِرُهُ مِنْ قِبَلِهِ الْعَذَابُ} [الحديد 13] هُوَ السُّوَرُ الشَّرْقِيُّ بَاطِنُهُ الْمَسْجِدُ وَمَا يَلِيهِ وَظَاهِرُهُ وَادِي جَهَنَّمَ
