Is there a specific curriculum for acquiring knowledge of the Qur’an and Sunnah, for inviting people to Islam, especially when there are no nearby schools available?

It is recommended to be diligent in seeking knowledge and memorizing the Noble Qur’an, with a daily schedule for that. Read the abridged books in every field before the comprehensive ones, and memorize the mutūn (concise texts) if possible. Acquire commentaries on books, especially those by Sheikh Ibn Uthaymeen. Seek a companion who can assist in seeking knowledge. Dedicate daily time to other sciences such as Tawhid (definition) (monotheism), Hadith (definition), and Fiqh (jurisprudence). Seek Allah’s help in seeking knowledge and in dawah (calling to Islam). Neither shyness nor arrogance should prevent one from seeking knowledge and asking questions.
