Does the deceased hear the supplication of his visitor?

Question:
And other than that, does he take pleasure in it? And regarding his command that it be repeated or not? Or that it not be repeated, that he decides what comes to him?

Answer:
Allah knows best. This is among the matters of the Hereafter. Shaykh al-Islam Ibn Taymiyyah and Ibn al-Qayyim say that the reports have become widespread that the deceased knows who visited him and hears his speech. Allah knows best. I do not know what is in the reports, nor do I know what this is. May Allah know best about it.
The bottom line is that the conditions of the graves are among the matters of the Hereafter that no one knows except Allah. So we carry out what the Messenger (peace and blessings be upon him) commanded us to do, which is visiting them and making supplication for them. As for whether they hear or do not hear, or know or do not know, Allah knows best about that, even if whoever said it said it. Yes.
