5ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنْ عَبْدِ الله بْنِ الْمُغِيرَةِ عَنْ عَبْدِ الله بْنِ سِنَانٍ قَالَ قُلْتُ لأَبِي عَبْدِ الله (عَلَيْهِ الْسَّلام) كَيْفَ التَّسْلِيمُ عَلَى أَهْلِ الْقُبُورِ فَقَالَ نَعَمْ تَقُولُ السَّلاَمُ عَلَى أَهْلِ الدِّيَارِ مِنَ الْمُسْلِمِينَ وَالْمُؤْمِنِينَ أَنْتُمْ لَنَا فَرَطٌ وَنَحْنُ إِنْ شَاءَ الله بِكُمْ لاَحِقُونَ.
5. Ali ibn Ibrahim has narrated from his father from ‘Abd Allah ibn al-Mughirah from ‘Abd Allah ibn Sinan who has said the following: “I asked abu ‘Abd Allah , ‘How should one offer greeting of peace to the people of the graves?’ He said, ‘Yes, (it has an answer). Say, “(May Allah grant) peace to the dwellings of the Muslims and believing people. You have departed us and we, by the will of Allah, will join you.’””
