Hadith #60

مُحَمَّدُ بْنُ أَحْمَدَ بْنِ يَحْيَى عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ أَبِيهِ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنْ عُبَيْدِ اَللَّهِ بْنِ عَلِيٍّ اَلْحَلَبِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ: فِي رَجُلٍ أَمَّ قَوْماً فَصَلَّى بِهِمْ رَكْعَةً ثُمَّ مَاتَ قَالَ« يُقَدِّمُونَ رَجُلاً آخَرَ وَ يَعْتَدُّونَ بِالرَّكْعَةِ وَ يَطْرَحُونَ اَلْمَيِّتَ خَلْفَهُمْ وَ يَغْتَسِلُ مَنْ مَسَّهُ»

Muhammad ibn Ahmad ibn Yahya narrated from Ahmad ibn Muhammad, from his father, from Ibn Abi Umayr, from Hammad ibn Uthman, from Ubaydullah ibn Ali al-Halabi, from Abu Abdillah : Imam al-Sadiq said regarding a man who led a group in prayer and prayed one rak’ah with them, then died. Imam said: “They should appoint another man, count the rak’ah (that was prayed), lay the deceased behind them, and whoever touched him must perform ghusl (ritual washing).”
