وَ رُوِيَ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ أَنَّهُ قَالَ: قُلْتُ لِأَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ اَلْمَوْتَى نَزُورُهُمْ فَقَالَ «نَعَمْ» قُلْتُ فَيَعْلَمُونَ بِنَا إِذَا أَتَيْنَاهُمْ فَقَالَ «إِي وَ اَللَّهِ إِنَّهُمْ لَيَعْلَمُونَ بِكُمْ وَ يَفْرَحُونَ بِكُمْ وَ يَسْتَأْنِسُونَ إِلَيْكُمْ» قَالَ قُلْتُ فَأَيَّ شَيْءٍ نَقُولُ إِذَا أَتَيْنَاهُمْ قَالَ «قُلِ اَللَّهُمَّ جَافِ اَلْأَرْضَ عَنْ جُنُوبِهِمْ وَ صَاعِدْ إِلَيْكَ أَرْوَاحَهُمْ وَ لَقِّهِمْ مِنْكَ رِضْوَاناً وَ أَسْكِنْ إِلَيْهِمْ مِنْ رَحْمَتِكَ مَا تَصِلُ بِهِ وَحْدَتَهُمْ وَ تُؤْنِسُ بِهِ وَحْشَتَهُمْ «إِنَّكَ عَلىٰ كُلِّ شَيْءٍ قَدِيرٌ».
It was narrated from Muhammad ibn Muslim that He said: "I asked Imam Jafar ibn Muhammad Al-Sadiq (a.s): Do the dead know when we visit them?" Imam (a.s) said: “Yes, by Allah (swt), they know of your visits and they rejoice and find comfort in your presence” I said: "What should we say when we visit them?" Imam (a.s) said: Say; Allahumma jāfi al-arda ‘an junūbihim, wa ṣā‘id ilayka arwāḥahum, wa laqqihim minka riḍwānan, wa askin ilayhim min raḥmatika mā taṣilu bihi waḥdatahum wa tu’nisu bihi waḥshatahum, innaka ‘alā kulli shay’in qadīr. "O’ Allah (swt), make the earth light upon their sides, raise their souls to You, grant them Your pleasure, and send upon them from Your mercy that which connects their loneliness and soothes their desolation. Truly, You are powerful over all things."
