Some grave-worshippers argue for the permissibility of building domes over graves by citing the Green Dome above the grave of the Prophet ﷺ!

Question:
Honorable Shaykh, may Allah grant you success, he says: Some grave-worshippers argue for the permissibility of building domes over graves by citing the Green Dome above the grave of the Prophet (peace and blessings be upon him). They said: If it were forbidden, Allah would not have been pleased for it to be built over the grave of His Prophet.

Answer:
If Allah were pleased with it, you would have evidence that Allah is pleased with it, Glorified and Exalted is He. You are saying about Allah what you do not know. This dome was built by a sultan; it was built by one of the later sultans. It was not built by the command of the scholars or by their consultation. Also, the grave was not in the mosque; it was outside the mosque.
When the Prophet (peace and blessings be upon him) was buried in his house, why was he buried in his house and not in al-Baqi'? It was because it was feared that it would be made into a mosque to be venerated. So it was placed between the walls for its protection and safety in his house. It remained in his house, outside the mosque, during the caliphates of the Rightly Guided Caliphs, the caliphate of Mu'awiyah ibn Abi Sufyan, and the caliphate of 'Abd al-Malik ibn Marwan.
Until al-Walid ibn 'Abd al-Malik came and wanted to expand the Prophet's Mosque. He expanded it from the east and included the Prophet's chamber in it. This was not with the consent of the people of knowledge; rather, it was a sultan's action. This passed by you in Tathir al-'Aqidah by al-Shawkani. It passed by you, the mention of the Prophet's chamber and how it was outside the mosque. You encountered this in Tathir al-'Aqidah which we read here. Yes.
