What is the criterion for the establishment of the argument against the ignorant and the innovator?

Question:
A number of contemporary scholars have stated that a disbeliever—one who speaks words of disbelief or acts upon disbelief—does not become a disbeliever until the argument is established against him, and they have included the worshippers of graves in this category?

Answer:
This is due to their ignorance. The worshippers of graves are disbelievers, the Jews are disbelievers, and the Christians are disbelievers. However, when it comes to killing, they are given the opportunity to repent; if they repent, well and good, otherwise they are killed.
Q: The issue of the establishment of the argument?
A: The Qur'an has reached them: [Ibrahim:52]. The Qur'an has reached them, and among the Muslims: [Al-An'am:19], , [Al-Ma'idah:67]. The Messenger (peace and blessings be upon him) has conveyed the message, and the Qur'an has come. They are before us, hearing it on the radio and elsewhere, yet they do not care and do not pay attention. And when someone comes to warn them and forbid them from evil, they harass him. We ask Allah for well-being.
