حَدَّثَنِی مُحَمَّدُ بْنُ الْحَسَنِ قَالَ حَدَّثَنِی سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ هِلَالٍ عَنِ ابْنِ فَضَّالٍ عَنْ أَبِی حَمْزَهَ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ ع یَقُولُ مَا مِنْ شَیْ ءٍ أَعْظَمَ ثَوَاباً مِنْ شَهَادَهِ أَنْ لَا إِلَهَ إِلَّا اللَّهُ لِأَنَّ اللَّهَ تَعَالَی لَا یَعْدِلُهُ شَیْ ءٌ وَ لَا یَشْرَکُهُ فِی الْأَمْرِ أَحَدٌ.
8. Imam Muhammad Baqir (a.s.) says: There is nothing more rewarding than the testimony of ‘There is no God except Allah’ because Allah has not appointed anything equal to it and there is no partner of Allah in this matter.
