A lot of those who memorize Quran do not know the meaning of Ijazah. It is better to define it first. It is a license from the Sheikh who grants Ijazah to the student who will get this license that he has read the whole Quran without using the Moshaf with Al-tajweed and accuracy in memorizing and that he has become himself qualified to grant Ijazah to others who want to get Ijazah.
