[AH] Fathul-Bari Sharah Sahi Al- Bukhari (2 vols) – فتح الباری شرح صحیح البخاری

Know that many of these major sins – the majority of them except a few – most people are unaware about their forbiddance, and the threat and warning [associated with them] has not reached them…

It is upon the scholar to not be rash when dealing with a person who is ignorant [of these matters].

Rather, he should be gentle with him and teach him with the knowledge that Alkali has taught him, especially if the individual recently [embraced Islam and] left his period of ignorance, and he was raised in the distant lands of disbelief.”
