What does Islam say about false allegations leading to jailing of fellow Muslims?

Divorce wont take place if I signed the divorce papers. This is what I was thinking when I singed the divorce papers. I thought that untill and unless, I utter the word ‘Talaq’ in front of her or in her absence, then the divorce will take place. But after I signed the divorce papers, I came to know divorce has taken plan. As it was talaq-e-Bain, I requested my wife to come back in my life. But she didn’t believe and said that I have intentionally divorced her. With the help of her parents, she filed false dowry case just to take revenge. In the case, she made false allegations including the allegation like we once tried to kill her. And Allah knows it is not true. I was sent to jail. Her father bribed the cops and took my wife out of the house during her iddat period just to file a false dowry case. Believe me and Allah knows when I say this I love her alot but her family has taken a wrong way to take revenge. We are syeds and my parents are Haji and even they went to jail because of false dowry case. My question is what islam says about the muslims who put his fellow muslims in jail making false allegations? What islam says about the father who took her daughter out during her iddat period? When I requested her to come back but she refused, is the gunah of divorce is on me or on my wife? What islam says about my wife’s father who never tried to unite us even when I went to his home to bring back my wife? Please reply.
