The noble, virtuous scribes (angels) are great in that they are pure wisdom and light. They are considered generous since man makes use of their presence.
كَلَّا إِنَّهَا تَذْكِرَةٌ، فَمَنْ شَاءَ ذَكَرَهُ، فِي صُحُفٍ مُكَرَّمَةٍ، مَرْفُوعَةٍ مُطَهَّرَةٍ، بِأَيْدِي سَفَرَةٍ، كِرَامٍ بَرَرَةٍ [1]
“Nay! Surely it is an admonishment (The Qur’an is not the way the infidels have assumed) (The Qur’an is a book of admonishment). So let him who pleases, mind it and take a lesson. These excellent words are recorded in honored books, exalted, purified. These words are in the hands of noble, virtuous scribes(angels).”
