Is it permissible for me to send clips of the shirk (associating partners with Allah) of the grave-worshippers to one of those who sympathizes with them, because he has denied that such things occur among them?

Question:
Honorable Shaykh, may Allah grant you success. He says: Some of those who sympathize with the grave-worshippers deny the shirk (associating partners with Allah) events that occur at the graves, such as those that happen at al-Badawi, Karbala, and others. His question is: If I show him the video clips via the internet, which contain those shirk (associating partners with Allah) matters, so that he becomes convinced and believes that they are happening, is there any harm for me in doing so?

Answer:
If he becomes convinced, then praise be to Allah. But it appears that he will not become convinced. However, you are only establishing the proof against him; you show it to him in order to establish the proof against him. Otherwise, he is not convinced, and Allah knows best, rarely.
