وَعَنْ عَمْرِو بْنِ حَزْمٍ قَالَ: رَآنِي النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُتَّكِئًا عَلَى قَبْرٍ فَقَالَ: لَا تؤذ صَاحب هَذَا الْقَبْر أَولا تؤذه. رَوَاهُ أَحْمد
‘Amr b. Hazm told how, when the Prophet saw him leaning on a grave, he said, “Do not molest the occupant of this grave”; or, “Do not molest it.” Ahmad transmitted it.
