Question:
He says: Honorable Shaykh, may Allah grant you success, I see the word "mercy" written on the walls of al-Nasim cemetery and inside the cemetery, as well as the stones being painted with colors, green and blue. What is the ruling on that?

Answer:
May Allah reward you with good. Visit the cemeteries and observe the religious innovations (bid'ah) and other things present in them, and write to the authorities. Write to the authorities, to the Committee for Enjoining Good and Forbidding Evil, to the Department of Ifta. Report what you observe regarding the writings, paints, and other things happening in the graves. Yes.
