فَاقْرَءُوا مَا تَيَسَّرَ مِنَ الْقُرْآنِ
So recite whatever is easy for you of the Qur’an. (al-Muzzammil 73:20)
Here ma points to what is available or manageable for recitation. The verse does not name one fixed chapter or verse, and the book uses it to illustrate breadth of scope.
The expression ma tayassara also contains a qualification—what is manageable. Generality does not abolish qualifications; it embraces the instances that meet the stated description.
