According to search-discovered classical Islamic scholarship, the principle to 'recite as much as you may do with ease' (فَاقْرَءُوا مَا تَيَسَّرَ مِنَ الْقُرْآنِ) from Surah Al-Muzzammil, verse 20, is a foundational concept of divine mercy and ease (Tayseer) in Islamic worship. Ibn Kathir explains that this verse was revealed approximately a year after the initial, stricter commands for lengthy night prayers, thereby abrogating its obligatory nature and making it a recommended, voluntary act. This concession was granted because, as Al-Qurtubi notes, Allah in His infinite knowledge knew the believers' varying circumstances—some would be sick, others traveling for sustenance, and others engaged in struggle. The verse therefore replaces a difficult command with a manageable one, encouraging consistency over excess and establishing a core principle in Islamic law: difficulty brings about ease. This highlights a central theme of the Quran: that the faith is not meant to be a burden.
