"The Prophet said: 'Were it not for the fact that the people have recently left disbelief, and that I do not have enough funds to enable me to build it. I would have incorporated five cubits of the Hijr in it, and given it a door through which the people could enter, and another door through which they exit.'"  

أَنَّ النَّبِيَّ ﷺ قَالَ لَوْلاَ أَنَّ النَّاسَ حَدِيثٌ عَهْدُهُمْ بِكُفْرٍ وَلَيْسَ عِنْدِي مِنَ النَّفَقَةِ مَا يُقَوِّي عَلَى بِنَائِهِ لَكُنْتُ أَدْخَلْتُ فِيهِ مِنَ الْحِجْرِ خَمْسَةَ أَذْرُعٍ وَجَعَلْتُ لَهُ بَابًا يَدْخُلُ النَّاسُ مِنْهُ وَبَابًا يَخْرُجُونَ مِنْهُ  

"I said: 'O Messenger of Allah! Can I not enter the House?' He said: 'Enter the Hijr for it is part of the House.'"  

قُلْتُ يَا رَسُولَ اللَّهِ أَلاَ أَدْخُلُ الْبَيْتَ قَالَ ادْخُلِي الْحِجْرَ فَإِنَّهُ مِنَ الْبَيْتِ
