Clarification of the existence of the grave of the Prophet (peace and blessings be upon him) in al-Masjid al-Nabawi

Question:
He says: How do we interpret or justify the existence of the grave of the Prophet (peace and blessings be upon him) and his two companions in the Noble Prophet’s Mosque? The grave of the Prophet (peace and blessings be upon him) and his two companions is not in the mosque; it is in Aisha’s house.

Answer:
They were buried in the house of Aisha (may Allah be pleased with her), and Aisha’s house was outside the mosque during the time of the Rightly Guided Caliphs, during the time of Mu'awiyah ibn Abi Sufyan (may Allah be pleased with him), and during the time of 'Abd al-Malik ibn Marwan. All this time passed, and the grave of the Prophet (peace and blessings be upon him) was outside the mosque. The Caliphs would expand the mosque from the western, northern, or southern side, and they would leave the eastern side, which contains the Prophet’s chamber.
When al-Walid ibn 'Abd al-Malik came, he ordered his governor of Madinah, 'Umar ibn 'Abd al-'Aziz, to expand the mosque and include the chambers in the Messenger of Allah’s (peace and blessings be upon him) mosque. This was an error on his part, and the scholars did not agree with it. Rather, they rejected it, but he prevailed by his power and his governorship, and he carried out what he wanted without a fatwa from the scholars and without the consent of the people of knowledge. So the result is that the original grave is not in the mosque; it is outside the mosque. It was brought inside at this time we mentioned due to error and bad handling. Yes.
