وَ فِي رِوَايَةِ زُرَارَةَ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: «وَ إِنْ كُنْتَ خَلْفَ إِمَامٍ فَلاَ تَقْرَأَنَّ شَيْئاً فِي اَلْأَوَّلَتَيْنِ وَ أَنْصِتْ لِقِرَاءَتِهِ وَ لاَ تَقْرَأَنَّ شَيْئاً فِي اَلْأَخِيرَتَيْنِ فَإِنَّ اَللَّهَ عَزَّ وَ جَلَّ يَقُولُ لِلْمُؤْمِنِينَ، «وَ إِذٰا قُرِئَ اَلْقُرْآنُ » يَعْنِي فِي اَلْفَرِيضَةِ خَلْفَ اَلْإِمَامِ «فَاسْتَمِعُوا لَهُ وَ أَنْصِتُوا لَعَلَّكُمْ تُرْحَمُونَ » فَالْأَخِيرَتَانِ تَبَعاً لِلْأَوَّلَتَيْنِ.
In a narration from Zurarah about Imam Muhammad ibn Ali Al-Baqir عليه السلام, He said: "If you are behind an Imam, do not recite anything during the first two rak'ahs; instead, listen to his recitation and remain silent. Do not recite anything in the last two rak'ahs either, for Allah سبحانه وتعالى, the Almighty, says to the believers: 'When the Qur'an is recited, listen to it and be silent that you may receive mercy' (Surah Al-A'raf 7:204). The last two rak'ahs are a continuation of the first two."
