On the occasion for refuge, Abu Yusuf emphasizes the opening of prayer whereas Muhammad emphasizes the opening of Quranic recitation. Hanafis say basmalah and Ameen quietly, while Shafi‘is permit or prefer audibility in audible prayers. Hanafis classify al-Fatihah as wajib and Shafi‘is as a required pillar.
Each disagreement concerns a specific ruling or preferred manner rather than one undifferentiated practice.
