No need to answer every bharti post, since their bollywood movies mostly use Urdu instead of their national language hindi and they haven't come with a beautiful language like urdu this is another reason for bhartis to commit mass suicide,
And they want to talk about culture when everything they have is due to muslim marauders or hijacked from pakistan.
Pakistani Heritage and culture gives them nightmare.
Even bharti infested wikipedia says urdu originated during Ghaznavid Empire
From Wikipedia
Urdu arose in the contact situation which developed from the invasions of the Indian subcontinent by Persian and Turkic dynasties from the 11th century onwards,[13] first as Sultan Mahmud of the Ghaznavid empire conquered Punjab in the early 11th century, then when the Ghurids invaded northern India in the 12th century, and most decisively with the establishment of the Delhi Sultanate.
