who are the janpeetaward winners in urdu?

Answer 1

Is this what you were looking for? (I did a bit of digging before realizing that the name in English is 'Jnanpith Award'

Jnanpith Award

The country's highest literary award, the Jnanpith Award, is given to any Indian writer for his or her outstanding contribution in any of the 18 languages mentioned in the Eighth Schedule of the Constitution. It is given for outstanding contribution to creative writing in a specified period of 15 years but excluding the five years immediately preceding the year.The award was instituted in May 22, 1961. The total prize money for the scheme is Rs. 2.5 lakhs.

Award winners in Urdu, found in the lists in both the sources sited below:
1969 - Firaq Gorakhpuri - Gul-e-Naghma - Urdu
1989 - Qurratulain Hyder - Urdu
1997 - Ali Sardar Jafri - Urdu

I could not find any listing beyond 2003, so there must be at least 2, possibly 3 more recipients that are not listed.

Hope this helped!
