The Noble Quran is the eternal miracle of Prophet Muhammad (PBUH), because all the miracles of the prophets (PBUH) ended with their death, except our Prophet (PBUH), whose miracle is still preserved.
The first revelation of the Holy Qur’an that was revealed to Prophet Muhammad (PBUH) was ‘Read’ ‘اقرا’ from (Al Quran - 96 : 01) which shows the importance of acquiring knowledge by reading.
