Hadith 14493ـ مُحَمَّدُ بْنُ إِسْمَاعِيلَ عَنِ الْفَضْلِ بْنِ شَاذَانَ عَنْ صَفْوَانَ عَنْ إِسْحَاقَ بْنِ عَمَّارٍ عَمَّنْ سَأَلَ أَبَا عَبْدِ الله (عَلَيْهِ الْسَّلام) قَالَ أُصَلِّي خَلْفَ مَنْ لاَ أَقْتَدِي بِهِ فَإِذَا فَرَغْتُ مِنْ قِرَاءَتِي وَلَمْ يَفْرُغْ هُوَ قَالَ فَسَبِّحْ حَتَّى يَفْرُغَ.
3. Muhammad ibn ’Isma‘il has narrated from Ishaq ibn ‘Ammar from the one who has asked abu ‘Abd Allah (a.s.), has said the following: I once asked abu ‘Abd Allah (a.s.), ‘Can I perform Salah (prayer) behind one whom I do not follow and complete recitation when he has not yet completed?’ He (the Imam) said, ‘Say Tasbih (Allah is free of all defects) until he completes.’”
