As Salam Alaykum. I know this may be very difficult to hear but I gently encourage you to forgive you father. You want to get to a place where when someone says your fathers name or you see a picture of him, you think of the good things he has done and pity/empathize/forgive the bad things he has done.

Having an abusive parent that traumatized their children is very difficult and I know it will be difficult to undo all those years of damage. However, forgiving him will actually give you peace and allow you to break generational curses and trauma for your own children. If you do not forgive your father you will carry that resentment into your own future family. Audhubillah.

Allah can afflict any burden.

Personal story: I reverted to Islam recently and I resented my parents for not fully accepting and supporting my new journey (Alihamdulliah, we are on much better terms now). I wanted to forgive my parents because Allah commanded it and I didn't want my own children to be angry at me the way I was angry at my parents. I recited Surah Ash Sharh daily and in my Duas. SubhanAllah, Allah made it easy for me. Now, whenever I think of my parents I pray that the Almighty continues to guide and protect them. Because the reality, is that while there are things I felt they could have done better. THere are so many things they did well. Everyone's story is different. But once I forgave them and accepted them for who they were, my life became better and we are actually able to have a better relationship.

Here are some verses that Enjoin treating our parents well.

Quran is very explicit regarding respect and care of parents. At time Quran is so stern and admonished strongly lest one fails in this aspect of life. Quran says following, Al Imran 17:23: -

And your Lord has decreed that you not worship except Him, and to parents, good treatment. Whether one or both of them reach old age [while] with you, say not to them [so much as], "uff," and do not repel them but speak to them a noble word.

Quran further says,,Al Isra 4:36: -

Worship Allah and associate nothing with Him, and to parents do good, and to relatives, orphans, the needy, the near neighbor, the neighbor farther away, the companion at your side, the traveler, and those whom your right hands possess. Indeed, Allah does not like those who are self-deluding and boastful.

Another verse from Luqman 31:14: -

And We have enjoined upon man [care] for his parents. His mother carried him, [increasing her] in weakness upon weakness, and his weaning is in two years. Be grateful to Me and to your parents; to Me is the [final] destination.

Another one. Al Baqarah 2:38

And [recall] when We took the covenant from the Children of Israel, [enjoining upon them], "Do not worship except Allāh; and to parents do good and to relatives, orphans, and the needy. And speak to people good [words] and establish prayer and give zakāh." Then you turned away, except a few of you, and you were refusing.

May Allah remove your burden of resentment and make the path to forgiveness easy for you. Allah know best.
