THEY USED TO READ WITHOUT THE POINTS OR VOWEL SYMBOLS
Question:
Is it true that Qur'an was revealed with letters that had no points nor vowel symbols, indicating how they should be pronounced? If so, how then was it recited?
Answer:
Is it true that the early Mushafs that were recorded had no vowels, points or signs indicate when to pause; rather, points and vowels symbols were actually written during the time of the Tabi'in (Companion of the Prophets Companions). During the time of the Prophet Sallallahu alaihi wassallam , people would read, not from written, from their memory and from what they were taught by their teachers.
