Chapter 56 | One Performing Salah (Prayer) Partially behind an Imam Who then Asks Him to Lead because of Losing his Wudu’
9ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ ابْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادٍ عَنِ الْحَلَبِيِّ قَالَ سَأَلْتُ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) عَنْ رَجُلٍ أَمَّ قَوْماً فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ مَاتَ قَالَ يُقَدِّمُونَ رَجُلاً آخَرَ وَيَعْتَدُّونَ بِالرَّكْعَةِ وَيَطْرَحُونَ الْمَيِّتَ خَلْفَهُمْ وَيَغْتَسِلُ مَنْ مَسَّهُ.
9. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from Flammad from al-Halabiy who has said the following: “I once asked abu ‘Abd Allah , about a man who leads Salah (prayer) with a people and performs one Rak‘at; then he dies. He (the Imam) said, ‘They make another man to lead and count it as one Rak‘at, leave the dead body behind them and then take Ghusl (bath) for touching a dead body.’”
