Hadith #37

مُحَمَّدُ بْنُ يَعْقُوبَ عَنْ عَلِيِّ بْنِ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ اِبْنِ أَبِي عُمَيْرٍ عَنْ حَمَّادِ بْنِ عُثْمَانَ عَنِ اَلْحَلَبِيِّ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« إِذَا صَلَّيْتَ خَلْفَ إِمَامٍ لاَ يُقْتَدَى بِهِ فَاقْرَأْ خَلْفَهُ سَمِعْتَ قِرَاءَتَهُ أَوْ لَمْ تَسْمَعْ»

Muhammad ibn Yaqub from Ali ibn Ibrahim from his father from Ibn Abi Umayr from Hammad ibn Uthman from al-Halabi from Abi Abdillah , peace be upon him, who said: Imam al-Sadqi said: “If you pray behind an imam (of prayer) who is not to be followed, then recite behind him whether you hear his recitation or do not hear it.”
