The legacy of Prophet Muhammad
Prophet Muhammad's legislation applies to the worlds of Man and Jinn until the end times, turning away from his Sunnah is disbelief.
And We have sent you (O Muhammad) not but as a mercy for the (different) worlds. (Quran 21:107)
O our people (the Jinn)! Respond to Allah's Caller (i.e. Muhammad) and believe in him. He (Allah) will forgive you of your sins, and will save you from a painful torment (i.e. Hellfire). (Quran 46:31)
But no, by your Lord! They can have no faith, until they make you (O Muhammad) judge in all disputes between them, and find in themselves no resistance against your decisions, and accept them with full submission. (Quran 4:65)
Prophet Muhammad is the last of God's Messengers sent to guide mankind, there are no new Prophets after him.
Muhammad is not the father of any man among you, but he is a Messenger of Allah and the last of the Prophets. (Quran 33:40)
The coming of Prophet Muhammad was announced by previous Prophets and is blatantly clear in the Bible.
And (remember) when Jesus the son of Mary said: "O Children of Israel! I am the Messenger of Allah unto you, confirming the Torah before me, and giving glad tidings of a Messenger to come after me, whose name shall be Ahmad... (Quran 61:6)
"I have five names: I am "Muhammad" and "Ahmad" ("the praised one"), I am "Al-Mahi" (through whom Allah will eliminate disbelief), I am "Al-Haashir" (being the first person to be resurrected in the Hereafter), and I am also "Al-Aaqib" (there will be no Prophet after me)." (Hadith)
"I will raise them up a Prophet from among their brethren, similar to you (Moses), and will put My words in his mouth; and he shall speak unto them all that I shall command him." (Deuteronomy,18:18. See also John,16:7/16)
With his Second Coming, Jesus عليه السلام will rule using the Quran and Sunnah of Prophet Muhammad and Islam will be the only religion in the world.
He (Allah) it is Who has sent His Messenger (Muhammad) with guidance and the religion of truth (Islamic Monotheism) to make it victorious over all (other) religions even though the pagans/disbelievers hate it. (Quran 61:9)
"...(Jesus) the son of Mary will shortly descend among you people (Muslims), and will judge Mankind justly by the Law of the Quran (as a just ruler)... and all Mankind will be required to embrace Islam (with no other alternative)..." (Hadith)
The Prophet Muhammad was given many privilages not given to other Prophets because of the high status given to him by Allah.
"I have been given superiority over the other Prophets in six respects: I have been given speech which is concise but comprehensive in meaning; I have been mad victorious by the casting of fright (in the hearts of enemies); the spoils of war have been made lawful for me; the whole Earth has been made as a place of prayer for me and as a means of purification; I have been sent to all of Mankind and the line of Prophets is has finished with me." (Hadith)
The lasting miracle of the Prophet Muhammad is the Quran, which was revealed to him as a recitation as he could neither read nor write, yet its eloquence has not been matched by even experts in Classical Arabic and never will be.
And this Quran is not such as could ever be produced by other than Allah... Say: "Bring then a Chapter like unto it, and call upon whomsoever you can besides Allah, if you are truthful! (Quran 10:37-38)
The Prophet performed many miracles, such as providing large quantities of food and water from a small amount, splitting and rejoining the moon in two halves and many others.
The Hour has drawn near, and the moon has been cleft asunder. And if they see a Sign, they turn away and say: "This is merely continuous magic." They belied themselves and followed their own lusts. (Quran 54:1)
The Prophet Muhammad will be allowed to intercede on the Last Day for the believers as well as other special privileges such as the "Hawd" well of drink for the Believers before entry into Paradise, Kawthar being a river in Paradise and he will be raised to the elevated Praised Station and rank in Pradise.
Verily, We have granted you (Muhammad) al-Kawthar. (Quran 108:1)
"It may be that your Lord will raise you to the Praised Station. (Quran 17:79)
"My intercession is for those who committed major sins from my Ummah (the Muslims)." (Hadith)
The Prophet Muhammad was taken miraculously in one night from Makkah to Jerusalem and then to Heaven where he met some of the Prophets and was told about the five daily prayers by Allah Himself.
Glorified is He (Allah), Who took His slave (Muhammad) on a journey by night from the Sacred Mosque (in Makkah) to the Furthest Sacred Mosque (in Jerusalem)... (Quran 17:1)
The Prophet Muhammad foretold many prophesies that have already come true and many that speak of events yet to happen in the future.
The Romans have been defeated, in the nearest land and they after their defeat will be victorious, within three to nine years... (Quran 30:2-4)
"... Beware (of the Anti-Christ, "Dajjaal")! He is blind in one eye, whereas your Lord is not so. Between his (the Dajjaal's) eyes, will be written the word; "Kaafir" (disbeliever)." (Hadith)
