٤ وَ رَوَى سُلَيْمَانُ بْنُ عِيسَى عَنْ أَبِيهِ قَالَ قُلْتُ لِأَبِي عَبْدِ اللَّهِ (ع) كَيْفَ أَزُورُكَ وَ لَمْ أَقْدِرْ عَلَى ذَلِكَ قَالَ قَالَ لِي يَا عِيسَى إِذَا لَمْ تَقْدِرْ عَلَى الْمَجِيءِ فَإِذَا كَانَ يَوْمُ الْجُمُعَةِ فَاغْتَسِلْ أَوْ تَوَضَّأْ وَ اصْعَدْ إِلَى سَطْحِكَ وَ صَلِّ رَكْعَتَيْنِ وَ تَوَجَّهْ نَحْوِي فَإِنَّهُ مَنْ زَارَنِي فِي حَيَاتِي فَقَدْ زَارَنِي فِي مَمَاتِي وَ مَنْ زَارَنِي فِي مَمَاتِي فَقَدْ زَارَنِي فِي حَيَاتِي
4. Sulaymān ibn ‘Isā narrated from his father, who said: I asked Abā ‘Abdillāh (Imam Šādiq ), “How should I perform your Ziyārah if I am not able to (come to visit you?)” Imam  replied: O ‘Isā! When you are not able to come (to my Ziyārah), perform a Ghusl or Wuďū on a Friday, ascend to the roof of your house, establish two Rak’ah of prayers, and then turn toward the direction of my location. Verily those who come to visit me during my life (are like those who) have performed my Ziyārah after my death, and those who perform my Ziyārah after my death (are like those who) have come to visit me during my life.
