I agree. Learning is what matters.
Under the caption, Collection under Abu Bakar (rta), the word Suhuf is explained:
Suhuf means loose pieces of writing material, such as paper, skin, papyrus, etc.
Under the caption, Collection under Uthman (rta), the word Mushaf is explained:
Uthman ordered fourn companions, among them Zayd Ibn Thabit to rewrite the script in perfect copies. Mushaf (i.e. Masahif) means collected Suhuf brought together into a fixed order.
