Hadith

 حَدَّثَنَا مُحَمَّدُ بْنُ عَلِيٍّ مَاجِيلَوَيْهِ رَحْمَةُ اَللَّهِ عَلَيْهِ قَالَ حَدَّثَنِي عَمِّي مُحَمَّدُ بْنُ أَبِي اَلْقَاسِمِ عَنْ مُحَمَّدِ بْنِ عَلِيٍّ اَلْكُوفِيِّ عَنْ مُحَمَّدِ بْنِ سِنَانٍ عَنِ اَلْمُفَضَّلِ بْنِ عُمَرَ قَالَ قَالَ اَلصَّادِقُ ع كَذَبَ مَنْ زَعَمَ أَنَّهُ مِنْ شِيعَتِنَا وَ هُوَ مُتَمَسِّكٌ بِعُرْوَةِ غَيْرِنَا.

 Mohammed bin Ali Majilwayh, Allah may have mercy upon him, narrated to us from his uncle Mohammed bin Abi al-Qasim from Mohammed bin Ali al-Kufi from Mohammed bin Sinan from al-Mufaddhal bin Omar that Imam as-Sadiq (a) said: He who claims being one of our Shia while he is clinging to the handle of somebody else is surely telling a lie.
