Textual validity is the prerequisites of the authenticity of comprehension in all divine or non-divine texts. This can be tested by making sure that the original text has remained intact. Feiz Kashani has tried to show the textual validity of Quran in three ways. His first approach is to show the impossibility f distortion. The second is through cross-referencing by the immaculate imams to the existing text. The third approach is a piece-meal one and has been Feiz’s own edition to the existing validation approaches.
