Hadith 235 3ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنِ الْعَبَّاسِ بْنِ مَعْرُوفٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي نَجْرَانَ قَالَ كَتَبْتُ إِلَى ابي جعفر (عَلَيْهِ السَّلام) أَوْ قُلْتُ لَهُ جَعَلَنِي الله فِدَاكَ نَعْبُدُ الرَّحْمَنَ الرَّحِيمَ الْوَاحِدَ الاحَدَ الصَّمَدَ قَالَ فَقَالَ إِنَّ مَنْ عَبَدَ الاسْمَ دُونَ الْمُسَمَّى بِالاسْمَاءِ أَشْرَكَ وَكَفَرَ وَجَحَدَ وَلَمْ يَعْبُدْ شَيْئاً بَلِ اعْبُدِ الله الْوَاحِدَ الاحَدَ الصَّمَدَ الْمُسَمَّى بِهَذِهِ الاسْمَاءِ دُونَ الاسْمَاءِ إِنَّ الاسْمَاءَ صِفَاتٌ وَصَفَ بِهَا نَفْسَهُ.
3. Ali ibn Ibrahim narrated from Al-Abbas ibn Marouf from Abd al-Rahman ibn Abi Najran, who said: "I wrote to Abu Ja'far al-Baqir (as) or I told him, 'May God make me your sacrifice, we worship the Most Merciful, the Most Compassionate, the One, the Unique, the Eternal.' He said, 'Indeed, whoever worships the name without the Named has associated partners (with God), disbelieved, and denied. He has not worshipped anything. Rather, worship God, the One, the Unique, the Eternal, who is named by these names, not by the names themselves. The names are attributes, and He has described Himself with them.'"
