John Burton argues, naskh become more important following the establishment of the principle of As-Shafi’i that hadith of Muhammad overruled all other reports from Companions or others on the same subject. This doctrine led to the growth in hadith attributed to the Prophet. Since “far too many" of these hadith "were mutually contradictory”—some contradicting the Quran -- “their use might court the risk” of failing to follow divine law (the view of some of the Mu’tazila of the era). For proponents of the As-Shafi'i doctrine a practical problem was the contradictions would lead to an abandonment of basing Islamic law on prophetic hadith.
