سَأَلْتُ أَبَا عَبْدِ اللَّهِ ع عَنْ رَجُلٍ يُصَلِّي عَلَى جِنَازَةٍ وَحْدَهُ قَالَ نَعَمْ قُلْتُ فَاثْنَانِ يُصَلِّيَانِ عَلَيْهَا قَالَ نَعَمْ وَ لَكِنْ يَقُومُ الْآخَرُ خَلْفَ الْآخَرِ وَ لَا يَقُومُ بِجَنْبِهِ.
“I once asked abu ‘Abd Allah (a.s.), about a man who performs Salah (prayer) for a dead body alone. He (the Imam) said, ‘Yes, he can do so.’ I then asked, ‘Can two people perform Salah (prayer) for a dead body? He (the Imam) said, ‘Yes, but one of them stands behind the other and not on his side.’”
