Should a man whom Allah has guided and who has begun to regularly observe prayer and frequent mosques abandon reading "Majmu' al-Fatawa" by Sheikh al-Islam Ibn Taymiyyah at this stage, due to his lack of knowledge of Arabic and the Sharia sciences, and instead commit to one of the jurisprudential schools of thought as a gradual approach to seeking knowledge?

Seeking knowledge has its principles, manners, and tools. Whoever disregards them will err in understanding. We have previously mentioned programs for seeking knowledge and some beneficial books in previous fatwas. You can contact the Open Islamic Academy, which provides methodical instruction in the Islamic sciences.

Regarding the fatwas of Sheikh Al-Islam Ibn Taymiyyah: they are a great encyclopedia, but students of knowledge are advised to read them after studying condensed and simplified books on the fundamentals of the sciences and progressing through them.
