You have missed the whole point or willingly ignored it may be. Any new prophet can come with divine signs, not by changing Quran or hadith.
Do you know that promised Messiah came with a sign that no man can interefere with or has control over. This sign alone is enough for people with fear of God to accept him.

There are so many religion out there and they all claim that their Prophets/Gurrus/Imams came up with divine signs and obviously they all cannot be true when they differ to each others in core beliefs. I consider Mirza Ghulam Ahmed as fake divine personality with zero output or deliverance. Its my right to accept or reject his divine claims. I am sure you will also reject our Imam mahdi and Jesus because you already made up your mind about Mirza Ghulam being genuine Imam mahdi as well as 2nd coming of Jesus so you see thats where you differ with others mainstream Muslims. I think you guys also believe that Jesus was buried somewhere in Kashmir which again contradict with beliefs of other Muslims
I don't mind if Qadyani call me kafir because I am openly rejecting divine claims of your prophet Mirza Ghulam Ahmed . You should also not mind when others Muslims call you non Muslim because you add another divine personality Mirza Ghulam Ahmed to their religion Islam and create confusion not only for Muslims but also for those non Muslims who are interested to learn about core beliefs of Islam. You guys should not label apple as orange because they boht taste different. Chrsitian are not calling themselves jews when they are having different set of beliefs . Sikhs are not calling themselves Hindus when they believe in divine claim of Guru Nanak
Rest I firmly believe that Qadyani should be free to practice their beliefs even if others consider these beliefs as false or fabricated . They should face no discrimination or injustice from others that's why I was not supporting this move of government when they asked Atif mian to step down from EAC because religious beliefs of Atif mian dont discredit his knowledge and qualification in economics
So Jesus when he comes back will not be a prophet??
Simple answer is no because he will appear as one of the followers of Prophet Muhammad(PBUH). Read this for more to understand the Muslim perspective about Jesus which differ to qadyani version to great extent

Due to the fact that the Jews had become deaf and blind to the words of God and deviated from the teachings of Moses and the right path, Allah honoured Jesus عليه السلام with Prophethood and sent him as a messenger to the Israelites. Bearing all hardships Prophet Jesus عليه السلام spent all day and night conveying the message of Allah. Unfortunately, in spite of his tremendous effort, most of the Israelites did not accept his message. Seeing that the poor and weak were becoming inclined towards him and fearing they would lose their leadership, the Jews secretly conspired to kill him. However, Allah saved Prophet Jesus عليه السلام from their wicked scheme and gave him greater dignity by raising him alive to the heavens.
Allah (God) says in the Quran, "They did not kill him (Jesus) and nor did they crucify him (Jesus), but it seemed to them (as if it was Jesus being crucified) and those who differ there in, are in doubt. They have no certain knowledge. They are following nothing but conjecture for surely they did not kill him but Allah raised him up to him." (Surah Nisa)
Allah (God) says in the Quran "When Allah says, Jesus; I will take thee to me and I will purify thee of the unbelievers" (Surah Al-Imran)
These verses clearly prove that the Jews did not kill Prophet Jesus عليه السلام and that he was raised alive to Heaven. It is due to verses like those mentioned above and many authentic Hadiths, we Muslims believe that Prophet Jesus عليه السلام is alive in Heaven at this moment in time. We further believe due to the following verses and authentic
The Return (Second Coming) of Jesus Christ عليه السلام
The Bible describes in a vivid language the corruption, destruction, and death typifying the End of Times. We see the godly forces confronting the evil forces of Satan, the Anti-Christ, and Gog and Magog. We learn that the cataclysmic events will take place in the Middle East. But still the picture needs to be completed.
Among these, the Quran and Prophet Muhammad صلى الله عليه وسلم have foretold the return of Jesus عليه السلام . Prophet Muhammad صلى الله عليه وسلم has prophesied about several events that will occur just before the advent of the day of judgment. The return of Jesus will occur AFTER the Anti-Christ (known in Islam as the Dajjal, meaning the Deceiver who claims to be God) appears and attempts to deceive people into worshipping him. Then, Jesus (the Messiah) عليه السلام will descend from Heaven, pursue and kill the Anti-Christ, and destroy the savage and unbelieving armies of Gog and Magog, and bring peace and brotherhood to the World.
Christians will recognize the truth and accept Jesus عليه السلام as a Muslim Prophet and Messenger of God. The religion of God (Islam) will justly rule the World. There will be no more oppression or wars, and peace will prevail. Furthermore, there will be no need to collect Jizyah (tax levied on Christians & Jews in Islamic states) because Christianity and Judaism will end. Every human being will be financially well-off and no one will accept charity. Jesus عليه السلام will perform Hajj (pilgrimage), marry, begets children, and die after living on Earth. His death will signal the beginning of the last days for humanity before the Day of Judgment.
The Wisdom in the Descent of Prophet Jesus عليه السلام
Sunni Muslim scholars have given many different reasons for the return of Prophet Jesus عليه السلام to this World. A few are listed below:
1) The Jews believe that they killed Prophet Jesus عليه السلام , Allah will send him before the end of time to prove that they did not killed him and that he is alive. It is Jesus who will fight the Jews and kill their leader, the Dajjal. (Ibn Hajar Al'Asqalani's
Fathul-Bari)
2) Some scholars have said that Prophet Jesus عليه السلام found many virtues of the followers of Prophet Muhammad صلى الله عليه وسلم in the Bible and thus he prayed to Allah to make him amongst the nation of Prophet Muhammad صلى الله عليه وسلم . Allah answered his prayer and he will return for the second time as one of the followers of Prophet Muhammad صلى الله عليه وسلم . (Ibn Khathir)
Evidence from Quran about the Second Coming of Jesus عليه السلام
159. وَإِن مِّنْ أَهْلِ الْكِتَابِ إِلاَّ لَيُؤْمِنَنَّ بِهِ قَبْلَ مَوْتِهِ وَيَوْمَ الْقِيَامَةِ يَكُونُ عَلَيْهِمْ شَهِيدًا
Allah (God) says in the Quran, "
There shall not be anyone from People of the Book, but shall believe in him before his death and on the Day of Resurrection, he (Jesus) shall be a witness against them." (Quran 4: 159)
Furthermore, Allah (God) also says in the Quran,
"And he (Jesus عليه السلام) shall be a Sign (for the coming of) the Hour (of Resurrection); therefore have no doubt about it (the Hour). And follow me (Allah), this is a Straight Path." (Quran 43: 61)
3. Jesus عليه السلام
as one of the Major Signs of the Day of Resurrection
Jesus' return to Earth is a major sign of Qiyamah (Day of Resurrection):
Allah (God) says in the Quran,
"And he (Jesus عليه السلام) shall be a Sign (for the coming of) the Hour (of Resurrection); therefore have no doubt about it (the Hour). And follow me (Allah), this is a Straight Path." (Quran 43: 61) Ibn Abbas has said that the meaning of this verse is that Prophet Jesus' عليه السلام descent is a sign of Qiyamah. (Musnad Ahmad)
Huzaifa bin Usaid reported that Prophet Mohammad صلى الله عليه وسلم suddenly came to us while we were talking. He asked,
"What are you talking about?" We replied
"We were talking about the Last Hour." Prophet (s) said,
"It will never come until you see ten signs before it. He then mentioned the Smoke, the Dajjal (Anti-Christ), the Daabba, the Rising of the Sun from the place of its setting, the Descent of Jesus son of Mary (from Heaven), Yajuj and Ma'juj (Gog & MaGog)..." (Sahih Muslim)
3) It is the Law of Allah that anything created from the Earth has to be buried in the Earth and not in the Heavens. Thus, he will return to the Earth for the second time, kill the Dajjal, live for a period of time and then he will die a natural death and will be buried near the Prophet Mohammad صلى الله عليه وسلم . (Muhammad Al-Barzanji's book
Al-Isha'ah li Ashrat AsSaa'h).
