A:
If the situation is as you mentioned, you should keep advising your father with the help of those who might convince him among relatives, friends or neighbors. If he becomes righteous, praise be to Allah (Exalted be He); otherwise, seek Allah's help and keep away from your father's unlawful money. You have to earn your living yourself, behave kindly with him, and follow the path of those who turn to Allah (Exalted be He). This is not considered disobedience to your father on your part. May Allah guide him and you to the straight path.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
