فَاقْرَءُوا مَا تَيَسَّرَ مِنَ الْقُرْآنِ
Meaning: Recite whatever is easy of the Quran (73:20).
The verse is used to establish recitation in general, without explicitly naming al-Fatihah. A prophetic instruction likewise mentions reciting what one knows from the Quran.
اقْرَأْ مَا تَيَسَّرَ مَعَكَ مِنَ الْقُرْآنِ
Meaning: Recite what is easy for you from the Quran.
