Ottoman transcription phenomena are varied such as ellipsis, addition, alternation, "Al-Hamz", displacement, and conjunction. This research focuses on addition particularly the addition of the Arabic letter "Al-Alef" in the Holy Quran transcription. My research sheds light on the origins and regulations of "Al-Alef" addition in a try to find answers for plenty of questions raised about the rules for such addition. Hence, this research is certain to prove that the regulations, implications, and benefits of this addition are of major importance and cannot be ignored or passed by superficially.
