Why aren't the letters چ‎, گ‎ or پ‎ found in the Qur'an?

Question

I am wondering about the following three letters: * چ‎ – Che * گ‎ – Gaf * پ‎ – PeThese three letters are not in the Qur'an (not even a single time).Is there any reason behind that?

Answer 1

Because these are not Arabic letters, they are Persian.

Answer 2

The letters you mention originate from non-Arabian languages that use modified forms of the original letters (Jeem, Kaaf, Ba).Urdu and Farsi are some great examples. The Qur'an is only and entirely in Arabic, and so those modified letters are not used.
