There is no doubt that the differences among the Quranic Redings include singular, dual, plural, gender; conjugation; declension (syntax); increase & decrease; anastrophe; substitution and dialects. These factors are all closely related to the linguistic phone which is affected by them. Scrutinizing the reading of Hafs Bin Asim reveals that this Reading is the nearest one which discloses an important aspect of the Quranic phonetic miracle through the phonetic study such as the open & closed, long & short syllables, place and manner of articulation, difficulty & easiness in pronunciation as well as the lips shape. Moreover, the harmony of all these with the context in the Quranic expression. The results are reflected in many sections like: 1. Intensity & laxity; 2. Glottalization & non-glottalization; 3. Voice and voiceless 4. Increase and decrease.
