1) The Seal of the Prophets عليهم الصلاة والسلام. This is due to Allaah's statement سبحانه و تعالى:
"Muhammad is not the father of any of you men, but rather he is the Messenger of Allaah and the seal (i.e. last) of the prophets. And Allaah is Ever All-Aware of everything." (Sooratul-Ahzaab, 33:40)
2) The leader of the Messengers عليهم الصلاة والسلام.
3) The eemaan (faith) of a servant is not complete until he believes in his message صلى الله عليه وسلم, due to Allaah's statement سبحانه و تعالى:
"But no by your Lord they can have no faith (eemaan), until they make you (O Muhammad صلى الله عليه وسلم) a judge in all disputes between them, and find in themselves no resistance against your decisions, and accept (them) with full submission." (Sooratun-Nisaa', 4:65)
This applies likewise for the prophets عليهم الصلاة والسلام that were sent to their respective peoples - each one of them holds the same status with respect to his nation.
4) Mankind will not be judged except with the occurrence of his intercession.
5) His nation (ummah) will have precedence over all the other nations, with regard to entering Paradise. This is based on the generality of his statement صلى الله عليه وسلم:
"We are the last (but) the foremost on the Day of Judgement." [1]
6) He is the owner of the Banner of Praise. He will carry it on the Day of Judgement, and those who give praise will be below it, due to the hadeeth of Abu Sa'eed al-Khudree رضي الله عنه who reported that the Prophet صلى الله عليه وسلم said:
"I will be the leader of the sons of Aadam on the Day of Judgement, and I do not say this to boast. In my hand will be the banner of praise and I do not say this to boast. And there will not be a prophet from Aadam nor his like on that Day, except (that he will be) below my banner. And I will be the first for whom the earth will split asunder (i.e. during resurrection) and I do not say this to boast."
Imaam at-Tirmidhee رحمه الله reported this hadeeth and Imaam Muslim رحمه الله transmitted the first and last parts of it. [2]
7) He is the possessor of the most praiseworthy station صلى الله عليه وسلم. This refers to the achievement that both the Creator سبحانه و تعالى and the creation send their praises upon. This is due to Allaah's statement سبحانه و تعالى:
"And in some parts of the night (also) offer the Salat (prayer) with it (i.e. recite the Quran in the prayer), as an additional prayer (Tahajjud optional prayer Nawafil) for you (O Muhammad صلى الله عليه وسلم). It may be that your Lord will raise you to a praiseworthy station (maqaam mahmood - a station of praise and glory, i.e. the highest degree in Paradise)." (Sooratul-Israa', 17:79)
This station will come as a result of his virtues on the Day of Judgement, such as interceding and so on.
8) He is the possessor of the Fountain (Hawd). It is a large fountain with many people arriving at it.
9-11) He is the leader of the Prophets عليهم الصلاة والسلام, their spokesman, and the possessor of their intercession. This is based on the hadeeth of Ubay ibn Ka'ab رضي الله عنه that the Prophet صلى الله عليه وسلم said:
"When it will be the Day of Judgement, I shall be the Imaam (leader) of the Prophets, their spokesman and the possessor of their intercession, and I do not say this to boast."
Imaam at-Tirmidhee رحمه الله reported this hadeeth and declared it hasan. [3]
12) His ummah is the best of nations, due to Allaah's statement سبحانه و تعالى:
"You are the best of people ever raised up from mankind. You enjoin Al-Ma'ruf (i.e. Islamic Monotheism and all that Islam has ordained) and forbid Al-Munkar (polytheism, disbelief and all that Islam has forbidden), and you believe in Allaah. And had the people of the Scripture (Jews and Christians) believed, it would have been better for them; among them are some who have faith, but most of them are Al-Fasiqun (disobedient to Allaah - and rebellious against Allaah's Command)." (Soorah Aali 'Imraan, 3:110)
As for Allaah's statement سبحانه و تعالى:
"O childred of Israa'eel! Remember My Favour which I bestowed upon you and that I preferred you above all of mankind." (Sooratul-Baqarah, 2:47) then it refers to mankind at their time. [4]
