Imam al-Rida (AS) said, ‘Some of our traditions are ambiguous like the ambiguous verses of the Quran, and some are clear like the clear verses of the Quran. Then refer its ambiguous ones to its clear ones, and do not follow its ambiguous ones [blindly] without referring to its clear ones lest you go astray.
الإمامُ الرِّضا (عَلَيهِ الّسَلامُ) : إنَّ في أخْبارِنا مُتَشابِهاً كمُتَشابِهِ القُرآنِ ، ومُحْكَماً كمُحْكَمِ القُرآنِ ، فَرُدّوا مُتَشابِهَها إلى مُحْكَمِها ، ولا تَتَّبِعوا مُتَشابِهها دُونَ مُحْكَمِها فتَضِلّوا .
