If the reality is as you have mentioned, it will be permissible for you
to do `Umrah on behalf of your deceased mother. You should repent for the way you treated your mother and ask Allah's forgiveness, pray for her and give charity on her behalf.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
