 أَبِی ره قَالَ حَدَّثَنِی سَعْدُ بْنُ عَبْدِ اللَّهِ عَنْ أَحْمَدَ بْنِ أَبِی عَبْدِ اللَّهِ عَنْ أَبِیهِ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنْ أَبِی خَالِدٍ عَنْ مُحَمَّدِ بْنِ مُسْلِمٍ عَنْ أَبِی جَعْفَرٍ ع قَالَ: أَدْنَی الشِّرْکِ أَنْ یَبْتَدِعَ الرَّجُلُ رَأْیاً فَیُحِبَّ عَلَیْهِ وَ یُبْغِضَ.
3. My father (rah) said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Abi Abdillah from his father from Muhammad b. Sinan from Abi Khalid from Muhammad b. Muslim from Abi Ja’far  who said: “The lowest form of polytheism is to invent a new religion and hate and love according to it.”
