I have read multiple interpretations regarding this verse. I found that scholars have mentioned different sayings about the latter portion of the ayah "أنا له لحفظون" about who does the pronoun له refer to in the verse. Some say this refers to Prophet Muhammad S.A.W. I just wanted to know that is there any principle due to which the widely one is accepted is it refers to الذكر itself and if it's agreed upon. Please guide me I'm trying to clear my doubt regarding this for a quite long. Since there's an akhbari scholars saying that there is differences in interpretation of this ayah and therefore cannot be used as evidence for divine preservation. He also quotes Sunni tafsirs to support his claim. His arguments are causing doubts in my mind.
