Chapter 36 | One’s Saying, No One Deserves to be Worshipped Except Allah
1ـ عِدَّةٌ مِنْ أَصْحَابِنَا عَنْ أَحْمَدَ بْنِ مُحَمَّدٍ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ عَنْ مُحَمَّدِ بْنِ الْفُضَيْلِ عَنْ أَبِي حَمْزَةَ قَالَ سَمِعْتُ أَبَا جَعْفَرٍ (عَلَيهِ السَّلام) يَقُولُ مَا مِنْ شَيْءٍ أَعْظَمَ ثَوَاباً مِنْ شَهَادَةِ أَنْ لا إِلَهَ إِلا الله إِنَّ الله عَزَّ وَجَلَّ لا يَعْدِلُهُ شَيْءٌ وَلا يَشْرَكُهُ فِي الأمُورِ أَحَدٌ.
1. A number of our people have narrated from Ahmad ibn Muhammad from Muhammad ibn Ali from Muhammad ibn al-Fudayl from abu Hamza who has said the following: “I heard abu Ja’far saying, ‘There is nothing greater in rewards than testifying to the truth and believing in the meaning of the testimony of belief in Allah: ‘No one deserves to be worshipped except Allah’, Allah, the Most Majestic, the Most Holy, Who has no equal and no one shares Him in any issue. ’”
