conditions of a wali for marriage of a sayyedah

I am writing to seek your esteemed guidance on a matter that has been weighing heavily on my heart. I am a Sayeddah and have been practicing Islam throughout my life. Recently, I have expressed my intention to marry a Muslim convert who has devoted many years to the practice of Islam. However, my father, despite the gentleman's adherence to Islam, objects to the union on grounds unrelated to Islamic principles. He cites the convert's non-Muslim origin, Pakistani background, and lack of a Muslim family as reasons for his disapproval. I am struggling to reconcile his decision with Islamic teachings, which emphasize the importance of a partner's faith rather than lineage. Given my Sayeddah status, I am particularly interested in understanding the conditions for a Wali in this scenario. How does Islam view a marriage proposal from a Muslim convert, and what guidance can you provide regarding the role of a Wali in such circumstances? I am earnestly seeking your wisdom and expertise to navigate this situation in accordance with Islamic principles. Your guidance will be immensely appreciated as I strive to find a resolution that aligns with both my faith and familial relationships. JazakAllah Khair for your time and consideration.
