Insurance policy issue

Sir, my husband bought a house in Dubailand on December 10th 2015. He had paid half of the total amount rest he had taken a loan from Noor Bank.

But very unfortunately he was diagnosed with cancer from 2016 February. He has been undergoing treatment since then. But he has been paying the bank EMI every month. But the treatment for his cancer did not work and he passed away on April 2017. We informed Bank.

My husband has made insurance (Takaful) while buying this property. I have also informed about the bank about this. But they are asking for 6 months bank details of husbands which is not possible for me to give.

Now what is the option left in front of me, Sir? Sir, plz help with your advice.
