Is a person held accountable for unlawful acts of which he was unaware, whether he was ignorant or among the students of knowledge who did not ascertain the ruling before their death?

Excuse due to ignorance varies depending on individuals and issues. A new convert to Islam or an illiterate person raised in a non-Muslim environment is not held accountable for forbidden acts committed out of ignorance. However, one who grew up in an Islamic environment is held accountable for what is clearly forbidden and commonly known among Muslims, and his ignorance is not excused. He is excused in matters whose prohibition is not well-known. Al-Suyuti said: "Whoever is ignorant of the prohibition of something that is common among most people, his claim of ignorance is not accepted, unless he is a recent convert to Islam or grew up in a remote desert where such matters are obscure, like the prohibition of adultery, murder, theft, alcohol, speaking during prayer, and eating while fasting." If a Muslim dies having committed something for which his ignorance is excused, he is not held accountable for it, as Allah Almighty says: "And We would not punish until We send a messenger."
