وَمَا كَانَ بِطَرِيقِ التَّوَاتُرِ فَمَصْرُوفٌ عَنْ ظَاهِرِهِ إِنْ أَمْكَنَ
If a narration is firmly established by mass transmission, a sound alternative interpretation is sought where possible.
The certainty of a report and the certainty of its apparent interpretation are not identical. A narration may be well established while a particular word or incident admits more than one serious reading. One can then examine its meaning without simply discarding the evidence.
Interpretation is not a device to evade any unwelcome text. A legitimate interpretation should be supported by language, context and coherent doctrinal reasoning. Arbitrary or strained readings are not automatically justified.
