The response to those who cite the Prophet’s (peace and blessings be upon him) single instance of preaching in the cemetery as proof that preaching in the cemetery is always permissible

Question:
He says: Honorable Shaykh, may Allah grant you success. One of the brothers preaches to people in the cemetery every day, raising his voice and prolonging his address to them. We informed him that adhering to this practice is contrary to the Sunnah, but he said, “The Prophet (peace and blessings be upon him) preached at the grave.” What is the correct position in this matter?

Answer:
The grave. Yes, meaning he made the grave a pulpit. The Prophet (peace and blessings be upon him) did not do this regularly. It happened once when he arrived and the grave had not yet been finished. He and his Companions sat down waiting for the preparation of the grave to be completed, so he (peace and blessings be upon him) preached to them. He did not do this regularly, nor did he make it a regular practice. Therefore, making it a regular practice and treating it as a Sunnah is a mistake. Yes.
