I have relatives who fall into religious innovations (bid'ah) and acts of shirk (associating partners with Allah); what is their ruling, and are they excused due to their ignorance?

Question:
He says: Honorable Shaykh, may Allah grant you success. He says: Some of my relatives fall into this bid'ah, which is dhikr (remembrance of Allah) using the singular name, saying "Allah, Allah," or using the pronoun, while swaying to the right and left to some poems accompanied by music. They call it a "dhikra" (remembrance gathering), and in it, Honorable Shaykh, there are words of shirk, such as supplicating to other than Allah and calling for aid from the awliya (close friends of Allah). His question is: What is the ruling on these relatives, and are they excused due to their ignorance in this? Also, they slaughter at the graves, at the graves of the awliya. What is obligatory for me toward them, and what is their ruling?

Answer:
It is obligatory to teach them. They are ignorant; perhaps they saw people doing this and assumed it was correct, especially those who claim affiliation with knowledge. They saw them or were ordered by them to do this, and they trusted them, saying, "This is it," or they did this thing out of ignorance. So you remind them and explain it to them, perhaps Allah will grant them acceptance, and you will obtain the reward, if Allah wills. Otherwise, what is the benefit of students of knowledge and the benefit of scholars except that they explain things to people, remind people, and spread what they have learned in their lands and among their relatives? This is the benefit of learning knowledge. Yes.
