What was narrated concerning the niche-grave being recommended
حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، حَدَّثَنَا أَبُو عَامِرٍ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ جَعْفَرٍ الزُّهْرِيُّ، عَنْ إِسْمَاعِيلَ بْنِ مُحَمَّدِ بْنِ سَعْدٍ، عَنْ عَامِرِ بْنِ سَعْدٍ، عَنْ سَعْدٍ، أَنَّهُ قَالَ: أَلْحِدُوا لِي لَحْدًا وَانْصِبُوا عَلَىَّ اللَّبِنَ نَصْبًا كَمَا فُعِلَ بِرَسُولِ اللَّهِ ـ صلى الله عليه وسلم ـ .
It was narrated that Sa’d said: “Make a niche-grave for me, and block it up with bricks as was done for the Messenger of Allah (ﷺ).”
