How can I balance my efforts in calling my family, including my parents, to religious adherence, with developing my scholarly knowledge in the fields of Sunnah, Aqidah, Sirah, and Fiqh?

We advise you to continue what you are doing, while taking care to transmit the sayings of trustworthy scholars, and not to presume to interpret or speak about the meanings of Hadith (definition) without knowledge, and to choose a simplified style. For Creed, we recommend Al-Ashqar's series "Al-Aqidah in Light of the Qur'an and Sunnah (definition)," and Al-Jaza'iri's "Aqidat al-Mu'min." For Tafsir (definition), we recommend the abridged Tafsir Ibn Kathir or Tafsir al-Sa'di. We also advise you to pay attention to the book "Riyadh as-Salihin." And it is imperative to invite your father to prayer and urge him to perform it; you can seek assistance from the book "Why Do We Pray?" by Muhammad Ismail al-Muqaddim.
