tulsa father stabbed in the heart at front door

My husband was stabbed 3 times. He was stabbed in the heart, it was a through and through, it made a 2 inch whole in his heart. He was also stabbed in the arm, it went completely through the arm. Gashed across the top of his head. He almost bled out before help arrived. He underwent 5 hours of open heart surgery . He may have permanent nerve damage in his hand, as of now it is swollen and his fingers are completely numb, he can not move that arm. Doctors say his recovery will take three months. As he was the main household earner, we'll be struggling with his hospital bills and keeping up with normal bills. We appreciate any help we can get.
