There is some issue with priority... modern Shudh Hindi (the standard literary dialect) only dates from the 19th century when it was essentially invented by a number of Hindu intellectuals mostly in Benares. Urdu is older, along with the lovely Hindi dialect Braj Bhasha (both dating from the mid 16th century onward). The earliest Hindavi writing is Kabir, from the the 13th century. Also, Panjabi is a complex relation, since it's also the same language, filtered through the gilded pen of Guru Nanak.
