Wishing to travel to study abroad but his mother refusing

Q 2: I am not aware of many religious matters, so I decided to learn the knowledge of the Shari`ah. When I told my family who live in `Ar`ar that I will join the Islamic University in Madinah to learn, my mother (Part No. 25; Page No. 218) objected. She fears that the premium (850 Riyals) paid by the university can not meet the needs of my wife and I. She, at first, got upset about this decision for this reason and for thinking that I want to live independently away from her, my father and my brothers. I eventually persuaded her after making many attempts to let me go to the university and she was not angry with me. I consulted my father concerning this matter, and he advised me not to go. He said that he had no objection if I saw that this decision was useful. My wife and I moved to Madinah and joined the university. During my visit to my family in the spring of 1409 A.H., I noticed that my father, who did not speak out against this, was not pleased with me going to Madinah. I am filled with remorse about this.My question is: What should I do, bearing in mind the following:1. I am in dire need to learn the knowledge of Shari`ah to be aware of my religion. I fear being tempted by this worldly life and wealth if I help my father in his business.2. The financial position of my family is excellent and they are not in need of my wealth. When I lived with them, my father used to financially support me and my wife. (Part No. 25; Page No. 219) He owns real estate, stores, and has many workers working for him.3. I have three brothers who are younger than me. Two of them are students, one studies in the eastern region, and the other studies in Al-Jawf region. The third brother is thirteen years old. My father is not very old and is able to attend to the family needs and drive my brothers to their schools.Please tell me your opinion on this issue. Should I continue to seek knowledge or forsake it and help my father in his business?
