Is a person excused by ignorance in matters of creed or in matters that expel one from the religion?

Question:
Is a person excused by ignorance in matters of creed or in matters that expel one from the religion?

Answer:
Answer: Excuse by ignorance is in two cases. The clear and apparent matters: one is not excused by ignorance in these if the Qur'an has reached him. The Qur'an forbids shirk (associating partners with Allah), it forbids kufr (disbelief), it forbids zina (unlawful sexual intercourse), it forbids riba (usury or interest). These are clear matters. If he hears them from the Qur'an and he is an Arab, he understands them. And there are hidden matters that require scholars to explain them, the doubtful matters, as he (peace and blessings be upon him) said: "Indeed, the lawful is clear, and indeed, the forbidden is clear, and between them are doubtful matters, which many people do not know." So he asks about these and guides himself to the truth in them, and he does not remain in his ignorance. He is able to learn, to ask, and not remain in his ignorance.
