Here, famous Bollywood lyricist or poet Javed Akhtar says that translation of The Holy Quran was done in Sindhi language, 700 years prior to when it was done in Urdu for the very first time. We all are aware of Akhtar claiming to be a secularist, atheist and rationalist. Despite all that plus his criticism towards Pakistan, he's still a target of Hindutva fanatics who accuse him of being a Hinduphobic plus soft towards Jihadists and D-Company.
However, by the remark he has strengthened propaganda of Hindutva's little cousin in Pakistan aka Sindhutva, in other words Sindhi nationalism, in their narrative of 5000 year old civilization. Proponents of Sindhudesh always love to tamper with historical facts and want to expel Mohajirs, Punjabis, Pashtuns and anyone else whom they think doesn't belong to Sindh Dharti Ma.

Watch the following video by Dr. Nadeem Rizvi of Matruka Sindh where he clearly rebuts the claim.
