Is there another way to enter Paradise besides the path of "mothers' feet" for someone who has not seen his mother for two years and she does not wish to see him?

You must be dutiful to your mother and obey her, even if she is a polytheist or abusive, for the dutifulness to parents does not cease to be an obligation upon you. It is one of the gates of Paradise. Paradise has eight gates, among them the Gate of Prayer, the Gate of Jihad, the Gate of Charity, and the Gate of Ar-Rayyan for those who fast.
