1ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ النَّوْفَلِيِّ عَنِ السَّكُونِيِّ عَنْ أَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ لاَ تُطَيِّنُوا الْقَبْرَ مِنْ غَيْرِ طِينِهِ.
1. Ali ibn Ibrahim has narrated from his father from af-Nawfafiy from af-Sakuniy who has said the following: “Abu ’Abd Allah (a.s.), has said, ‘You must not apply clay to the grave which is not of the clay of that grave.’”
