621. hadíth
وَ رَوَى مُحَمَّدُ بْنُ مُسْلِمٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ قَالَ: "أَدْنَى اَلشِّرْكِ أَنْ يَبْتَدِعَ اَلرَّجُلُ رَأْياً فَيُحِبَّ عَلَيْهِ وَ يُبْغِضَ".
Muhammad ibn Muslim narrated from Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (a.s) who said: "The slightest form of polytheism is when a man invents an opinion and then loves and hates based on it."
