Hanafis distinguish the fard of Quranic recitation from the wajib specification of al-Fatihah, differentiating the import of Quranic and hadith evidence. Shafiis classify al-Fatihah itself as an integral, especially in light of the hadith that there is no prayer for one who does not recite it.
لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِفَاتِحَةِ الْكِتَابِ
Meaning: There is no prayer for one who does not recite the Opening of the Book.
