سَعْدٌ عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ أَبِي عُمَيْرٍ عَنْ مُحَمَّدِ بْنِ إِسْحَاقَ وَ مُحَمَّدِ بْنِ أَبِي حَمْزَةَ عَمَّنْ ذَكَرَهُ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ:« يُجْزِيكَ إِذَا كُنْتَ مَعَهُمْ مِنَ اَلْقِرَاءَةِ مِثْلُ حَدِيثِ اَلنَّفْسِ»

Sa’ad from Ahmad ibn Muhammad from Muhammad ibn Abi Umayr from Muhammad ibn Ishaq and Muhammad ibn Abi Hamzah from someone who mentioned it from Abi Abdillah , peace be upon him, who said: Imam al-Sadiq said: “It suffices you, when you are with them, to recite like the whispering of the soul (hadith al-nafs).” (meaning to recite quietly to yourself)
