لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِفَاتِحَةِ الْكِتَابِ
Meaning: There is no prayer for one who does not recite al-Fatihah.
Shafi‘i reasoning reads “no prayer” as negation of validity. Hanafi reasoning distinguishes the general Quranic obligation of recitation from specification by solitary-prophetic report and therefore classifies specific al-Fatihah recitation as wajib. The issue is interpretation and evidentiary hierarchy, not denial that the hadith exists.
