Hamzah In Hafs Reading Contradicting Quresh Reading
The answer to this article is given on another thread. The article does not provide any concrete evidence to prove that the Ottoman was ever involved in the spread of Hafs Qirat. The references to the existence of Qirat e Amma had already been there in the earliest centuries. So, there has always been Qirat e Amma which took the name of Hafs in scholarly circles because Hafs used to follow the Qirat Amma and did not use His preferences like some other recitores.
