Writing the names of the deceased on some graves, and some people painting them with colors, is this permissible?

Question:
He says: Honorable Shaykh, may Allah grant you success, people are now writing the names of the deceased on some graves, and some of them paint them with colors, is this permissible?

Answer:
All of this is not permissible. Painting them with colors is like plastering them. The Prophet (peace and blessings be upon him) forbade plastering graves, so do not color them with any color. As for placing an ambiguous marker, such as a line or a stone that he places on it, which no one knows except him as a marker, there is no harm in that. As for coloring them, the Messenger (peace and blessings be upon him) forbade it. Or writing a name; the Prophet (peace and blessings be upon him) forbade writing on graves, so do not write names on them, or the date of death, or his biography, as the superstitious people do. They make the grave like the others, so the graves become similar, and one does not know this one from that one except the one who knows the grave of his relative only, without a marker, meaning or a distinctive feature for him over the other graves. He places a stone on it that no one knows except him, or he draws a line as a marker on it, which no one knows except him. Yes.
