٦ حَدَّثَنِي مُحَمَّدُ بْنُ الْحَسَنِ عَنْ مُحَمَّدِ بْنِ الْحَسَنِ الصَّفَّارِ عَنْ أَحْمَدَ بْنِ مُحَمَّدِ بْنِ عِيسَى عَنْ إِسْمَاعِيلَ بْنِ سَهْلٍ عَنْ أَبِي أَحْمَدَ عَمَّنْ رَوَاهُ قَالَ قَالَ لِي أَبُو عَبْدِ اللَّهِ (ع) إِذَا بَعُدَتْ عَلَيْكَ الشُّقَّةُ وَ نَأَتْ بِكَ الدَّارُ فَلْتَعْلُ عَلَى أَعْلَى مَنْزِلِكَ وَ لْتُصَلِّ رَكْعَتَيْنِ فَلْتُومِ بِالسَّلَامِ إِلَى قُبُورِنَا فَإِنَّ ذَلِكَ يَصِلُ إِلَيْنَا
6. Muĥammad ibn Ĥasan narrated to me from Muĥammad ibn Ĥasan Al-Šaffār, from Aĥmad ibn Muĥammad ibn ‘Isā, from Ismā’ǐl ibn Sahl, from Abǐ Aĥmad (Ibn Abǐ ‘Umayr), from someone who narrated to him, who said: Abū ‘Abdillāh (Imam Šādiq ) said to me: If you live far (from us) and there is a great distance between you and us, ascend to the highest place of your house, establish two Rak’ah of prayers, point toward our graves, and say Salām to us, for verily it will reach us.
