Being undutiful to your father is prohibited. Allah (Exalted be He) says,
And your Lord has decreed that you worship none but Him. And that you be dutiful to your parents.
The Prophet (peace be upon him) mentioned being undutiful to parents as one of the seven great destructive sins:
The gravest sin is associating partners with Allah, and being undutiful to parents...
You have to treat your father kindly and ask him to give you whatever you need using good words. (Part No. 25; Page No. 224) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
