وَعَنْ جَابِرٍ
قَالَ: نَهَى رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: أَنْ يُجَصَّصَ الْقَبْرُ وَأَنْ يُبْنَى عَلَيْهِ وَأَنْ يُقْعَدَ عَلَيْهِ
Jabir said God’s messenger forbade that graves should be plastered with gypsum, that any erection should be built over them, and that people should sit on them.
