The Excuse of Ignorance in Shirk and the Arrival of the Argument

Question:
And it is not that Shaykh Ahmad, may Allah be praised, says that the error of knowledge is such that what the disabled people are doing now—praying to the idols out of ignorance—does not invalidate their faith as long as the argument has not reached them. He says that Allah, Glorified and Exalted, has said, "And whoever has been informed," and these people have not been informed that this is disbelief. Then, if they are asked about the jinn, they say that it is hungry. So how is the man in this state of bitterness?

Answer:
By Allah, my brothers, this is a false argument, because the Qur'an is clear, and most people memorize the Qur'an. In the most extreme form of refuting the mushrikin (those who associate partners with Allah) and refuting shirk (associating partners with Allah), the matter is clear. So, if the Qur'an has reached a person—whether he heard it, read it, or memorized part of it—the argument has reached him. Until when has the argument reached him?
The Messenger (peace and blessings be upon him) says, and Allah revealed to him that he should say, "It has been revealed to me this Qur'an to warn you thereby and whoever it has reached." This means the Qur'an has reached them, and most of them memorize the Qur'an by heart, perhaps in the seven or ten recitations. So we say, has the Qur'an reached them? This is not correct. Yes, it is.
