Chapter 85 | Visiting of the Graves
9ـ مُحَمَّدُ بْنُ يَحْيَى عَنْ مُحَمَّدِ بْنِ أَحْمَدَ قَالَ كُنْتُ بِفَيْدَ فَمَشَيْتَ مَعَ عَلِيِّ بْنِ بِلاَلٍ إِلَى قَبْرِ مُحَمَّدِ بْنِ إِسْمَاعِيلَ بْنِ بَزِيعٍ فَقَالَ عَلِيُّ بْنُ بِلاَلٍ قَالَ لِي صَاحِبُ هَذَا الْقَبْرِ عَنِ الرِّضَا (عَلَيْهِ الْسَّلام) قَالَ مَنْ أَتَى قَبْرَ أَخِيهِ ثُمَّ وَضَعَ يَدَهُ عَلَى الْقَبْرِ وَقَرَأَ إِنَّا أَنْزَلْنَاهُ فِي لَيْلَةِ الْقَدْرِ سَبْعَ مَرَّاتٍ أَمِنَ يَوْمَ الْفَزَعِ الأكْبَرِ أَوْ يَوْمَ الْفَزَعِ.
9. Muhammad ibn Yahya has narrated from Muhammad ibn Ahmad who has said the following: “I was in Fayd (a place near Makkah). Ali ibn Bilal and I went to visit the grave of Muhammad ibn Isma’il ibn Bazi‘ and Ali ibn Bilal said, ‘The dweller of this grave narrated to me from al-Rida’ , the following: “If one visits the grave of his brother (in belief), places his hand over the grave and reads Surah 97 of the Holy Quran seven times he, on the distressful Day (of Judgment) will be granted full protection and peace.’””
