Yes there are. Malekotla was an oasis, and island of peace and harmony during the dreadful months of 1947 (July, Aug, Sept…).

Here is a relatively unbiased source that puts Muslim population in Malerkotla as 70%.
But do not take this news item by its title (it is misleading). the misery was caused by the closure of the border. But Muslims in Malerkotla are SAFE and GROWING.

BBC NEWS | South Asia | Muslims look to end misery of separation
some historical facts (not authenticated, so take it with a grain of salt).
And some interesting forum discussion (again take it with a grain of salt)
The bottom line is:
Panjabee Muslims in E. Punjab survived at least in Malerkotla.
Unfortunately for the rest of the E. Punjab, the number of Punjabi Muslim = zero
However sadly!
Non-Muslim Punjabis in Pak Punjab = zero.
except - a small Sikh population around holy sites such as: Nankana Sahib, and Gurudawar Punja sahib.
================
In summary - let me reiterate-
It is absolutely necessary for Paks to practice Iqra!
Otherwise they will continue believing in rumors and lies.
Oh by the way, I won’t count Gourgaon as true blue Punjabi “heartland” town. It is just a suburb of Delhi.
