BAQI AL- GHARQAD
Al-Baqi`al Gharqad is the graveyard or Cemetery of the people of Al-Madinah and has been so since the time of Prophet Muhammadﷺ. This cemetery has been the final resting place of the residents of Madinah, as well as those of nearby neighboring areas and of visitors, since the time of Hijrah. It was the preferred final resting place of the noble Companions (may Allah be pleased with them all). This is evidenced by the fact that the noble Companions (may Allah be pleased with them) are buried within. 
Among the notable Muslims interred there are the Mothers of the Believers (the Prophet's wives), with the exclusion of Khadijah and Maymunah (may Allah be pleased with them all). Also buried there are the Prophet's daughters, the Prophet's son Ibrahim, the Prophet's uncle `Abbas, the Prophet's aunt Safiyyah, and the Prophet's grandson Al-Hasan ibn `Ali (may Allah be pleased with them all).
Of all of the historic places in Madinah, it is the closest to Al-Masjid An-Nabawi (the Prophet's Mosque). It is located opposite the southeastern section of the wall of the masjid.
An imposing new, high marble-clad wall has been erected around the entire perimeter of Al-Baqi`, so that the old and new areas have been united. Its total area presently amounts to 56,000 square meters (13.8 acres). 
A'isha(R) reported (that whenever it was her turn for Allah's Messenger [ﷺ] to spend the night with her) he would go out towards the end of the night to al-Baqi' and say:
السَّلاَمُ عَلَيْكُمْ دَارَ قَوْمٍ مُؤْمِنِينَ وَأَتَاكُمْ مَا تُوعَدُونَ غَدًا مُؤَجَّلُونَ وَإِنَّا إِنْ شَاءَ اللَّهُ بِكُمْ لاَحِقُونَ اللَّهُمَّ اغْفِرْ لأَهْلِ بَقِيعِ الْغَرْقَدِ
Peace be upon you, abode of a people who are believers. What you were promised would come to you tomorrow, you receiving it after some delay; and God willing we shall join you.O Allah, grant forgiveness to the inhabitants of Baqi' al-Gharqad. Qutaiba did not mention his words:" would come to you". Sahih Muslim 974 
It is authentically reported from the Prophet (ﷺ) that he used to seek refuge from the punishment in the grave in his Salah (Prayer) and ordered his Sahabah (Companions) to do the same.Sahih al-Bukhari 6367, Sahih Muslim 588 and Abu Dawud 983 It is also authentically reported that after he (peace be upon him) offered Salat-ul-Kusuf (Prayer at the time of a solar eclipse), he gave a Khutbah (sermon) to the people asking them to seek refuge with Allah from the punishment in the grave. He also sought refuge with Allah from the punishment in the grave three times in Baqi' Al-Gharqad when he (ﷺ) was putting one of his Sahabah in the Lahd (a crevice on the side of a grave facing the direction faced for Prayer). If the punishment in the grave had not been authentically reported, the Prophet (peace be upon him) would not have sought refuge from it or asked the Sahabah to do so.
Narrated Masruq(R): `Aisha(R) said that a Jewess came to her and mentioned the punishment in the grave, saying to her, "May Allah protect you from the punishment of the grave." `Aisha then asked Allah's Messenger (ﷺ) about the punishment of the grave. He said, "Yes, (there is) punishment in the grave." `Aisha(R) added, "After that I never saw Allah's Messenger (ﷺ) but seeking refuge with Allah from the punishment in the grave in every prayer he prayed." Sahih al-Bukhari 1049, 1050 and 1372. 
From Al-Bara' ibn `Azib (may Allah be pleased with him) that he said, We were attending a funeral in Baqi' Al-Gharqad when the Messenger of Allah (peace be upon him) came and sat with us. We remained silent while he (peace be upon him) was digging the grave, until he said, "I seek refuge with Allah from the punishment in the grave." He repeated it three times, and then he said,
"When a believer is about to depart this world and move on to the Hereafter, there comes down to them from heaven angels with white faces like the sun, and they sit around them as far as the eye can see. They bring with them shrouds and perfumes from Jannah (Paradise). Then, the Angel of Death comes and sits by their head, and he says, ‘O good soul! Come forth to forgiveness from Allah and His pleasure.’ Thus, the soul comes out easily like a drop of water from the mouth of a water skin. When he seizes it, they do not leave it in his hand for an instant before they take it and put it in that shroud with that perfume, and there comes from it a fragrance like the finest musk in the world. Then, they ascend to heaven. Whenever they pass by any group of angels, they inquire, ‘Who is this good soul?’ They say, ‘It is so and so, the son of so and so', calling them by the best names by which they were known in the world, until they reach the nearest heaven. They ask for it to be opened to them; it is opened; and (the soul) is welcomed and accompanied to the next heaven by those who are closest to Allah, until they reach the seventh heaven. Allah then says: ‘Record the book of My slave in ‘Illiyyun (in the seventh heaven), and return them to Earth, for from it I created them; to it I will return them; and from it I will bring them forth once again.’
The soul is returned to the body, and two angels come who make the person sit up and they ask them, ‘Who is your Lord?’ They say, ‘Allah.’ They ask, ‘What is your religion?’ They say, ‘My religion is Islam.’ They ask, ‘Who is this man who was sent among you?’ They say, ‘He is the Messenger of Allah.’ They ask, ‘What did you do?’ They say, ‘I read the Book of Allah and I believed in it.’ Then a voice calls out from heaven, ‘My slave has spoken the truth,so prepare for them a bed in Jannah; clothe them from Jannah; and open for them a gate to Jannah.' Then there comes to them some of its fragrance, and the grave is made wide, as far as they can see. Then there comes a man with a handsome face, elegant clothes and a good fragrance, who says, ‘Receive the glad tidings that will bring you joy this day.’ They say, ‘Who are you? Your face is one which brings glad tidings.’ He says, ‘I am your righteous deeds.’ They say, ‘O Lord, hasten the Hour so that I may return to my family and my wealth.’ On the other hand, when a disbeliever is about to depart this world and move to the Hereafter, angels come down to them from heaven with black faces, bringing sackcloth, and they sit around them as far as the eye can see. Then the Angel of Death comes and sits by their head, and he says, ‘O evil soul, come forth to the wrath and anger of Allah.' Then the soul disperses inside the body, and comes out cutting the veins and nerves, like a skewer passing through wet wool. When he seizes it, they do not leave it in his hand for an instant before they take it and put it in that sackcloth, and there comes from it a stench like the foulest stench of a dead body on the face of the earth. Then they ascend to heaven. Whenever they pass by any group of angels, they inquire, ‘Who is this evil soul?’ and they say, ‘It is so and so, the son of so and so', calling them by the worst names by which they were known in the world, until they reach the nearest heaven. They ask for it to be opened to them, but it is not opened.” Then the Messenger of Allah (peace be upon him) recited Allah's saying, ...for them the gates of heaven will not be opened, and they will not enter Paradise until the camel goes through the eye of the needle (which is impossible). Surah Al-A'raf, 7: 40
Allah (Glorified and Exalted be He) then says, 'Record the book of My slave in Sijjin in the lowest earth, and return them to the earth, for from it I created them; to it I will return them; and from it I will bring them forth once again.’ So the soul is cast down.” Then, he (peace be upon him) recited Allah's saying, ...and whoever assigns partners to Allâh, it is as if he had fallen from the sky, and the birds had snatched him, or the wind had thrown him to a far off place. (Surah Al-Hajj, 22: 31) Then the soul is returned to the body, and two angels come who make that person stand and they ask them, ‘Who is your Lord?’ They say, ‘Oh, oh, I don’t know.’ They ask, ‘Who is that man who was sent among you?’ They say, ‘Oh, oh, I don’t know.’ A voice calls out from heaven, ‘Prepare for them a bed in Hellfire and open for them a gate to Hellfire.’ There comes to them some of its heat and hot winds, and the grave is constricted until their ribs are squeezed. Then, there comes to them a man with an ugly face, shabby clothes, and a foul stench, who says, ‘Receive the bad news, for this is the day that you were promised.’ They inquire, ‘Who are you? Your face is one which forebodes evil.’ He says, ‘I am your evil deeds.’ They say, ‘O Lord! Do not let the Hour come.’ Abu Dawud 4753 and Musnad Ahmad Vol.4: pg296 
Sulaiman b. Buraida narrated on the authority of his father that the Messenger of Allah (ﷺ) used to teach them when they went out to the graveyard. One of the narrators used to say this in the narration transmitted on the authority of Abu Bakr:
السَّلاَمُ عَلَى أَهْلِ الدِّيَارِ - وَفِي رِوَايَةِ زُهَيْرٍ - السَّلاَمُ عَلَيْكُمْ أَهْلَ الدِّيَارِ مِنَ الْمُؤْمِنِينَ وَالْمُسْلِمِينَ وَإِنَّا إِنْ شَاءَ اللَّهُ لَلَاحِقُونَ أَسْأَلُ اللَّهَ لَنَا وَلَكُمْ الْعَافِيَةَ
" Peace be upon the inhabitants of the city (i. e. graveyard)." In the hadith transmitted by Zuhair (the words are):" Peace be upon you, the inhabitants of the city, among the believers, and Muslims, and God willing we shall join you. I beg of Allah peace for us and for you." Sahih Muslim 975
There is no proof of Saying Jannatul Baqi or Jannatul Mua’laat. There is no proof that every person buried in “Baqi ul Gharqad” will be entering paradise.
Some people refer Al-Baqi al Gharqad(Graveyard)' as Jannatu Baqi , it is inappropriate because some people are believing that all those who are buried are jannati(will go to paradise), many people are still getting buried in Baqi. So How can we confirm that these people are in Jannah witout any Proof although it is right that the one who is Muslim and Muwahhid if he died In-sha-Allaah he will get intercession (Shafath) of Prophet Muhammad (May Allah honour Him and Grant Him peace). “Whoever of you is able to die in Madinah, let him do so, for I will intercede for the one who dies in it,” Shaykh Al Albanee declared it sahih in Sahih at-Targhib wat-Tarhib’ 1192 and Ibn Majah 3112
