«لَا صَلَاةَ لِمَنْ لَمْ يَقْرَأْ بِفَاتِحَةِ الْكِتَابِ»
Meaning: There is no prayer for one who has not recited the Opening of the Book.
Shafi‘i jurists apply it to followers as well. The Hanafi explanation treats followers as a special case in light of listening and the imam’s recitation. The disagreement is interpretative rather than a denial of the hadith.
