Stones for unbelievers

8. "If ye be in doubt concerning the revelation which we have send down into our servant, produce a chapter like unto it and call your witnesses, beside God, if ye say truth. But if ye do it not, nor shall ever be able to do it, justly fear the fire whose fuel is men, and stones prepared for the unbelievers." (2:21, 22)

The writer has argued that Maulvi Fiazi did make a Quran like it. This is a claim that shows lack of knowledge of the Quran. Writing something does not make it like it or superior to it:

Produce a verse like it!
In this same topic, the writer has argued that the Puranas say that Malechhas are doomed to hell. Malechha refers to foreigners and in that particular case it refers to some foreigners in general and not in particular. Prati Sarag Parv III Khand 3 Adhay 3 Shloka 5 to 8 refer to a Malechha as the pride of mankind. From that we see that the context is different.
