What is the ruling on one who believes that the prophets and messengers have the power to cause benefit or harm by the permission of Allah?

Question:
He says: Honorable Shaykh, what is the ruling on one who believes that the dead prophets and righteous people have a right or share in exercising power, and in causing benefit and harm, by the permission of Allah, with clarification regarding the types of tawhid (the oneness of Allah)? May Allah reward you with good.

Answer:
This is a mushrik (one who associates partners with Allah), the one who claims that someone exercises power alongside Allah, whether from the angels, the prophets, the messengers, or the righteous people. The one who says that there is someone who shares with Allah in exercising power in this universe is a mushrik, and may Allah protect us from that, it is shirk akbar (major shirk).
Because no one exercises power in this universe except Allah (Exalted and Majestic is He) alone, and the angels, messengers, prophets, and righteous people are created servants who do not exercise power, especially if they are dead. How does a dead person exercise power?
Why did he not exercise power over himself? Why did he not come out of the grave? If he exercises power, why does he remain in the darkness of the grave and the burial niche? Why does he not come out? O Glorified is Allah! How strange are some minds, how are such falsehoods promoted to them?
And his saying "by the permission of Allah" is a matter of lying and promotion. Allah did not give permission, Allah did not give permission to anyone to exercise power with Him in this universe, yes.
