I want to ask as to where is the location of the grave of our beloved Prophet Muhammad (s)? Please provide with certain chains of narrations from authentic hadiths, thanks!
The Prophet (pbuh) was buried in the same room in which he died. It was one of the rooms in which he lived with one of his wives. His rooms were all attached to the Prophet’s mosque. Please see excerpt from Hayat ul Qulub by Allamah Majlisi below:
“Kulaini and Shaykh Tusi etc. have narrated through authentic chains of narrators that the Messenger of Allah (S) was shrouded in three garments: One was a red sheet and two pieces of Yemenite cloth. Moreover, it is narrated from Imam Ja’far Sadiq (a.s.) that Abbas came to Amirul Momineen (a.s.) and said, “People have decided that the Prophet should be buried in Baqi and Abu Bakr will lead the funeral prayers.”
When Imam Ali (a.s.) came to know that the hypocrites were ready to create mischief, he came out and said, “O people, indeed, the Messenger of Allah (S) after his life and death was our Imam and leader and he himself had told us that he should be buried at the place where he passes away. Since they were more interested in usurping the Caliphate, they did not argue and said, “Do as you like.” Thus he stood in the front and recited the funeral prayer. After that he told the companions and ten persons at a time prayed in congregation. Then Amirul Momineen (a.s.) stood up among them and recited the following verse:
إِنَّ اللَّهَ وَمَلَائِكَتَهُ يُصَلُّونَ عَلَى النَّبِيِّ ۚ يَا أَيُّهَا الَّذِينَ آمَنُوا صَلُّوا عَلَيْهِ وَسَلِّمُوا تَسْلِيمًا
“Surely Allah and His angels bless the Prophet; O you who believe! call for (Divine) blessings on him and salute him with a (becoming) salutation.” Then the people also recited this verse and invoked blessings on the Holy Prophet (S) and then went out. Till the people of Medina and surrounding areas invoked the blessings.”
