Non-practicing Muslim parent

Asalamualaikum. As a Muslim, how do I come to terms with a parent who did not show me kindness and mercy when I was a child. The most crucial years of my life were filled with criticism, abuse and put-downs, which went on for years. How do I deal with such a parent as an adult, because it was their actions that resulted in my years of trauma and unhappiness. I only understood the ramifications of their actions when I got older. It is painful and I've tried to make peace with my past and forgive my parent. However, I struggle with them still living a very hypocritical life, with no remembrance of Allah and without a care in the world for the hereafter, while I strive to be a better Muslim. I feel anger, resentment and guilt too. What should I do if my own parent is like this?

Wa'alaykumsalaam Wa Rahmatullah

if this was something in the past, then you may need to forgive them and ask Allah for firmness in the religion.

If this is still happening and they are preventing you from practicing your religion, then you may need to look for an alternative place near there and practice your religion.

You may not disobey them or treat them in an ill manner.

They are your parents at the end of the day- treat them well and if ever you feel that your religion is in danger - then you may get a place next to them but a different roof.

If you are unable to do so, then you should bear patient and ask Allah to open your way in shaa Allah and He will indeed.

Allah knows best
