The Syntactic Justification for the Qur'anic Recitations in "Lataif Al-Isharat" by Qastalani (Died in 923) 1437 AH = 2015.

Abstract

Al-Qastalani did not compare preference among the recitations whether they were recurrent ones or extra illuminated four ones. In case there would be any choice, it would be syntactically oriented for it is the most eloquent, renowned and widely used by Arabs. He views that the four recitations mentioned in his book added to the ten recurrent ones were illuminating where there is nothing to contradict with such as words additives. These recitations were correct, reliable and widely knowing. In addition, they were attached to the recurrent ones even though the recitations did not get to the point. They were called irregular according to recurrent recitations just because they were outstandingly supported.
