Is the story of Malik ibn Dinar, which includes his communion with graves and the authenticity of his saying, "They all vanished, and there is no informant; and they all died, and the news died," authentic, and can it be used as an argument for the permissibility of communing with the dead?

The story mentioned has appeared in several books and was narrated by Ibn al-Jawzi and Ibn Asakir. However, we have not found the ruling of the hadith scholars on their chains of transmission. Ibn Asakir's chain of transmission includes a narrator accused of fabricating hadith. This is a story of admonition that does not entail any action, nor can it be used to prove that the dead hear the words of the living.
