:salam2:
JazakaAllah khayran for your reply. Those are the hadeethes I read and know, but I still don't get the need to move the masjid in the rooms where the graves are
. I am not a scholar, but please what part am I not getting?
I hope I am not giving hard time to noone I just want to understand.
salam sister;
Your question show how wise you are. Here a details to what happen to the mosque and the garve of our prophet (pbuh)
Why is the Prophet’s grave in his mosque even though it is forbidden to take graves as places of worship?
Question:
The hadeeth says, “May Allaah curse the Jews, for they have taken the graves of their Prophets as places of worship”. So how come the grave of the Prophet (peace and blessings of Allaah be upon him) is inside his mosque in Madeenah?.
Answer:
Praise be to Allaah.
The scholars have discussed this issue, in the past and more recently, and they refuted those who quote the fact that the grave of the Prophet (peace and blessings of Allaah be upon him) is inside his mosque as evidence that it is permissible to take graves as places of worship, or to include graves in mosques. We will quote the fatwas of some of our prominent scholars, which discuss in detail the matter raised in the question.
1 – Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him) said:
There is a specious argument put forward by those who worship graves, namely the fact that the grave of the Prophet (peace and blessings of Allaah be upon him) is in his mosque. The answer to that is that the Sahaabah (may Allaah be pleased with them) did not bury him in his mosque, rather they buried him in the house of ‘Aa’ishah (may Allaah be pleased with her). When al-Waleed ibn ‘Abd al-Malik expanded the Mosque of the Prophet (peace and blessings of Allaah be upon him) at the end of the first century, he incorporated the room into the mosque,
but he did wrong thereby, and some of the scholars denounced him for that, but he believed that there was nothing wrong with it for the sake of expanding the mosque.
It is not permissible for a Muslim to take that as evidence that mosques may be built over graves, or that people may be buried inside mosques, because that goes against the saheeh ahaadeeth, and because it is a means that may lead to shirk by associating the occupants of the graves in worship with Allaah. End quote.

2 – Shaykh Muhammad ibn Saalih al-‘Uthaymeen (may Allaah have mercy on him) was asked about the ruling on praying in a mosque in which there is a grave.
He replied:
Praying in a mosque in which there is a grave falls into two categories:
(i) Either the grave was there before the mosque, and the mosque was built over the grave. It is essential to shun this mosque and not pray therein, and the one who built it must knock it down; if he does not do so, then the Muslim authorities must knock it down.
(ii) Or the mosque was there before the grave, and the deceased was buried after the mosque was built. In the case the grave must be dug up, and the remains taken out and buried with the people (in the graveyard).
As for praying in such a mosque, it is permissible so long as the grave is not in front of the worshipper, because the Prophet (peace and blessings of Allaah be upon him) forbade praying in the direction of graves.
With regard to the grave of the Prophet (peace and blessings of Allaah be upon him) which is incorporated into his mosque, it is well known that the Mosque of the Prophet (peace and blessings of Allaah be upon him) was built before his death, and was not built over his grave. It is also well known that the Prophet (peace and blessings of Allaah be upon him) was not buried in the mosque, rather he was buried in his house which was separate from the mosque. At the time of al-Waleed ibn ‘Abd al-Malik he wrote to his governor in Madeenah, who was ‘Umar ibn ‘Abd al-‘Azeez, in 88 AH, ordering him to dismantle the Prophet’s Mosque and add to it the rooms of the wives of the Prophet (peace and blessings of Allaah be upon him).
‘Umar gathered the prominent people and fuqaha’, and read the letter of the caliph al-Waleed to them.
That caused them distress, and they said: “Leave it as it is, that is better.” And it was narrated that Sa’eed ibn al-Musayyib denounced the incorporation of ‘Aa’ishah’s room into the mosque, as if he feared that the grave would be taken as a place of worship.
Umar wrote a letter to that effect to al-Waleed, and al-Waleed sent word to him ordering him to carry out his instructions, so ‘Umar had no other choice. So you see that the grave of the Prophet (peace and blessings of Allaah be upon him) was not placed in the mosque, and the mosque was not built over it, so there are no grounds for those who try to quote this as evidence that people may be buried inside mosques or that mosques may be built over graves.
It is proven that the Prophet (peace and blessings of Allaah be upon him) said: “May the curse of Allaah be upon the Jews and the Christians; they have taken the graves of their Prophets as places of worship.” He said that as he was dying, as a warning to his ummah against doing what they did. When Umm Salamah told him of a church that she had seen in Ethiopia and the images therein, he said: “Those people, if a righteous man among them died, they would build a place of worship over his grave. They are the most evil of people before Allaah.” And it was narrated from Ibn Mas’ood (may Allaah be pleased with him) that the Prophet (peace and blessings of Allaah be upon him) said: “Among the most evil of people upon whom the Hour will come when they are still alive are those who take graves as places of worship.” Narrated by Imam Ahmad with a jayyid isnaad.
The believer should not accept to follow the ways of the Jews and the Christians, or to be among the most evil of people.
