A ---The greatest one is:

(1) the Great Intercession on the Day of Judgment, the Day of Reckoning. This is a specialty granted to Prophet Muhammad (Peace be upon him). It is the Maqam Mahmud (a station of praise and glory) that is promised by Allah the Almighty in His Statement, {It may be that your Lord will raise you to Maqam Mahmud (a station of praise and glory, i.e. the honor of intercession on the Day of Resurrection)}. (Al-Isra', 79)

That when Allah will gather the believers on the Day of Resurrection in the same way (as they are gathered in this life), and they will say, 'Let us ask someone to intercede for us with our Lord that He may relieve us from this place of ours.' Then they will go to Adam, Nuh (Noah), Ibrahim (Abraham), Musa (Moses), ('Isa) Jesus, and finally Muhammad and say, 'Don't you see the people (people's condition)?' all of them would say, 'I am not fit for this undertaking', save Muhammad who would say, "I am fit for this undertaking ". (Bukhari and Muslim)

(2) Intercession for opening the gate of Paradise. The first to enter therefrom is Prophet Muhammad (Peace be upon him), and the first Ummah (community or nation) to enter it is his Ummah.

(3) Intercession for the benefit of some people who are ordered to be admitted into Hell, not to enter it.

(4) Intercession for the benefit of some monotheists who were admitted into Hell to get out from it.

Narrated Abu Sa'id Al-Khudri (May Allah be pleased with him): The Prophet (Peace be upon him) says: "When the people of Paradise will enter Paradise and the people of Hell will go to Hell, Allah will order those who have had faith equal to the weight of a grain of mustard seed to be taken out from Hell. So they will be taken out but (by then) they will be blackened (charred). Then they will be put in the river of Haya' (rain) or Hayat (life) (the Narrator is in doubt as to which is the right term), and they will revive like a grain that grows near the bank of a flood channel.

Don't you see that it comes out yellow and twisted. " (Bukhari and Muslim)

(5) Intercession for raising the ranks of some people from among the residents of Paradise.

The last three ones (3, 4, 5) are not peculiar to Prophet Muhammad (Peace be upon him), but he is to be advanced before other Prophets, angels, protectors and pious men who will intercede on that Day. Then, Allah the Almighty will take out with His Mercy from Hell-fire peoples without any intercession, the number of which can not be counted by other than Allah the Almighty. .

(6) Intercession for lightening the torment of some disbelievers. This one is peculiar to Prophet Muhammad (Peace be upon him) for the sake of his paternal uncle as transmitted by Imam Muslim and other Hadith Compilations: Anas Ibn Malik (May Allah be pleased with him), reported:

Allah's Messenger (Peace be upon him) said that the Hell would continue to say: Is there anything more, until Allah, the Exalted and High, would place His foot therein and that would say: Enough, enough, by Your Honor, and some parts of it would draw close to the other." (Bukhari and Muslim)
