In 1893 Huzoor^(as) invited Muslim divines to hold an essay competition with him in Arabic. Huzoor^(as) revealed that God Almighty has bestowed him perfect command of Arabic language. Therefore no one can compete with him. No one accepted the invitation despite the fact that he gave this challenge many times over.

Huzoor^(as) made known in 1895 in his book Minan al-Rahman that all the languages of the world have originated from Arabic language. Therefore Arabic is the mother of all languages. He also asserted that Arabic is the language of God Almighty. He offered a cash prize of Rs. 5000 to anyone who could disprove this claim.

This was an amazing discovery as scholars have been investigating for a long time to find the most original language. European scholars had pointed to either Sanskrit or Pahlvi. The latest research however indicates that Arabic is the most original language, all others derived from it. (M. A. Mazhar has traced 13 languages to Arabic in his book: Arabic, the Source of All Languages, 1963)
